Absolutely a pitfall, but I've won some good bets with the Bills this year because they were undervalued by other bettors.
I have sworn off parlays and have discovered the world of player props. Take the Jets game for example. The O/U for Diggs receptions was a stupid low 3.5. Who in their right mind thought Diggs would have fewer than 4 catches against the Jets? Boom, easy money. Same with Josh Allen O/U 1.5 TD passes.
Here's one from yesterday: Singletary receiving yards: 19.5. Again a no-brainer. He ended up with 50. Now that the Bills and Allen are the darlings of the NFL it's going to be tougher to find those gems. I did lose on the Diggs O/U. It was 4.5 and he only got 4 receptions. Damn penalties.
