    This is along the lines of what I assumed you were referring to. And although you can obviously work out an advantage if there's moneyline to spread inefficiency, an objective win prob is not implied. Hence the spread could have been well off, and in hindsight it probably was.

    You work out the probability that team X will win (best to use some kind of model behind this rather than using The Prick's dartboard method something unquantifiable). If you calculate that the probability that X wins is greater than the probability implied by the odds, then it's a "good" bet. The higher the difference, the more "good" the bet.

    This helps with comparing spreads and MLs and the Superbowl example.

    It's not hindsight. Because you move in with a 15 outer on the flop (54%) and you don't hit, does that make it the wrong play? No. You have to think long term.

    all models are different. Because they are based on different factors. You can have two models picking opposite sides (or different win%) and both be technically correct.

    Absolutely. The prediction accuracy of your model is directly correlated to your level of success.

    all in with a 15 outer is the wrong play if they have trips you are way behind

    A 15 outer is NOT a 15 outer if the other player has a set. But thanks for arguing semantics.

    Another example that is related but shows a different point is getting 7-1 on a heart flush draw in limit hold'em. You call, believing you have 9 outs (ignore implied odds for this example). You miss, and the other guy takes down the pot. After the hand is over, two players tell you they folded hearts preflop and that you really only had 5 outs. Now, with this information you wouldn't go back and make the call but your call still had +EV based on all available information at the time you made your decision and the information you found out after the hand is irrelevant. And it's the same thing in sports betting. Before the season, based on all available info, if you could get Clemson -2.5 against Bama, that was a great bet. Based on information now available Bama would be a favorite, but that information is irrelevant to analyzing past bets as that information was not available at the time you made the bet and how you interpret available information is what is important in gambling. Hopefully that makes sense as I'm not sure I elucidated my point well.

    I'm just good at comparing past results and analyzing stats to pick winners in NCAAF, I guess I'm too lazy to do all that probability modeling, I'm like Brandon Lang in Two for the Money I don't need a computer to pick my winners, I'm smarter than a computer

    Well they can both be winning models but they can't both be correct. One or both would not be properly analyzing all of the available information.

    There's no limit to relevant info. All the way down to what a player had for breakfast. Handicappers always work on new ideas which prove more or less important.

    Relevant does not make it prognostic. There is a great deal of statistical data that can actually be pejorative to the accuracy of forecasting in your model.

    by relevent I do mean prognostic. The one with the most meaningful data will have a more accurate prediction. I do not believe that any model has close to all such data.
    Thats why advancement in the field is always possible.

    True to some extent. There is a limit to the available data that is both quantifiable and prognostic, however.

    of course. line shopping is very significant.

    I simply want to suggest that handicapping is not bound by any prevailing wisdom. There can always be new ways of finding and sorting info that prove superior.

    Yeah, considering discipline is the key in surviving as a sports bettor or handicapper I have decided to never bet nfl or mlb again. Im convinced unless you have inside knowlege of something going on in the long run you want make a profit in NFL especially. I took the ova in the second half what looked to be a lock to me and they made sure that wouldn't happen. Ely comes out and throws an interception (no where close to his man) in the first possession. Last two Giant possessions they walk the football up the field then throw an interception (next to last possession)and run the ball once within 12 yards of the goal line when that's what got them all the way down the field (both of the last 2 possessions). Im convinced they were told to do that.

    Ive been doing this long enough to understand you take the wins with the losses but I can also see when something is a hoax, fraud, or fix . Everyone is screaming Kimbo Slice is and was a fraud but noone ever calls these professional football and baseball leagues on their fixes.

    Smart move thegreat, I am tellin you I am a long-time sports gambler and I know many sports gamblers that bet frequently and all of them get killed at NFL, I don't even know anyone other than myself and the guys on here that bet MLB but just watching the recent games Sabathia meltdown, Lester meltdown and watching trash pitchers give up 1 run while the aces just walk batters and serve up homers you know that game is the king of inconsistency. How are you going to predict the Reggie Bush is going to outplay LT or vice versa, there is no way to predict the NFL hell Browns hadn't won a game and NYG hadn't lost a game and Browns right on cue destroyed the NYG and my wallet. What's the fukin sense of it, take the worst team in the league against the best? Would you take the worst college team ML against Alabama? Of course not and that's why it's more predictable, you already know who's going to win, it's virtually a foregone conclusion now all you need to do is judge the "style" of game they bring to the table to determine by how many, whether they launch the ball and run up the score or run the ball and consume the clock, whether their defense wins the games or their offense etc., hell in NFL you can't even be sure the best team will beat the worst (in MLB worst wins 1/3 of the time against the best) so how can you make a guess as to what the correct side of a 7 1/2 pt spread is? Take the worst team in the league +7 1/2 sounds retarded against the best team, but then you worry giving up more than a TD in the NFL so you take the best team ML and get blown out 35-14 by the worst team . NFL/MLB is nothing but heartbreaking losses and stresses, bet NCAAF and NCAAB and win for the year.

    the Browns were not winless, and these two teams had the same record last year, called perception vs. reality

    No money line would be posted in that theoretical game, but several four touchdown underdogs have won outright in NCAAF this year.

    The Brownies were about 3-1 dogs. 3-1 ain't no prohibitive favorite, noob.

    I picked the Browns because 1) they were playing at home 2) 8 points is a lot in the NFL 3) the Giants were undefeated and didn't need to win and 4) the Browns were 1-3 and needed a win.

    If the Giants were at home I would have probably brought the line down to 6.5 and went with New York, but I did get burned on the Giants against the Bengals earlier this year, too.

    Generally I pick Parlays instead of single bets, but I did hit on San Diego -6 Sunday night and Cleveland +8 Monday night. But I'm starting to realize you can't keep betting favorites "on the road" when they're laying more than a TD. Sometimes it works if the other team is just plain dominant, but many times when a team needs a win (like San Diego at home, or Cleveland), they get the job done.

    I lost big Sunday night on the Pats, had a good day sun but with bad money magement I bet way too much on the Pats to cover (got greedy I guess) they got blown out. I was so disgusted I made my wager on the Browns immediately after that game. My thought was getting 8 points at home on Monday night football in the NFL, I'll take my chances. I didnt want to wait to place my bet Monday because I was afraid that with all the Giants hype going into the game I may change my mind and there was a couple times yesterday I thought why did I pick the the Browns? Anyway there where more and more guys posting on here who (if you follow their picks they are right more often than not esp on these type of so called "trap games") going with Cleveland and that made me feel better about my pick. So I guess my advice is 1. Never go against a home dog at night esp 2. Dont get caught up in all the hype about a great team cant lose, all these guys are good. 3. Pay attention to these forums and certain post, they know alot about sports gambling and they will steer you right,(not always granted but most of the time they will give you enough clues that will help ya. You see this every week, my last man standing is already down to 15 people 100 started. Its not surprizing at all in this league when there's an upset.

    this is what i having problems with. unless you know some inside info, all information are public and delayed. seems to me poker, day trading and sports are pretty similar. no one knows what the hell is going on in the short term, and as long as you're not the biggest loser, you should be okay.

    There is no way in hell the Browns should have even been contenders in that game, it was bizarre.

    I don't think every game in the NFL is rigged, but I do start to wonder sometimes just how the worst team in the NFL can beat the best team on Monday Night Football, when it just so happens that the amount of bets coming in probably top any other game during the weekend.

    I have only won 1 bet on MNF so far this year I think....

    Oh well,
