been researching teasers and for the most part they really are dumb but if you have a parlay you really like its always fun to buy points as many as 16 at 5 dimes and cahs it....
iunderstand to get -120 u still NEED to hit ALL 4 teams but ur getting 10 points on the spread how many times are the lines within a bucket or two? alot.....
bet 4 nba favorites and add ten points to their final spread it it probably is close to a 1 to 1
If you know what you are doing, then its not dumb but it is very rare a 10 point teaser is +EV in the nba if you did the math to calculate the edge. More often than not, that edge will never be more than a small percentage points.
