In a shoot out, any team has a puncher's chance. The ML on Detroit is just too good. So I made two $20 parlays based on the Lions winning:

PARLAY (3 TEAMS)
NFL - DETROIT ML +475 (sat.)
NBA - TOTAL o176.5 -110 (CHICAGO vrs ATLANTA) (sat.)
NFL - NY GIANTS -3 -105 (sun.)

$20.00 / $408.64

PARLAY (3 TEAMS)
NFL - DETROIT ML +475 (sat.)
NBA - TOTAL u176.5 -110 (CHICAGO vrs ATLANTA) (sat.)
NFL - NY GIANTS -3 -105 (sun.)

$20.00 / $408.64

The second bet in the parlays could be any wager that is settled before the Giants game. If Detroit wins on Saturday, then I am guaranteed a net of $368 if the Giants win the game on Sunday. This beats betting $40 on the ML for the Lions, which pays off $190. I could also hedge the wager on Sunday to lower my risk. This is just a fun bet that cranks up the payoff on a huge underdog (Detroit) that just might be the round 1 upset of the weekend.
