Have no data to back this up, but noticed it after the Padres lost 14-3 on opening day.
They come back and win 4-0 as a plus 2-1 dog.
Always bet this in NFL if a team lost by 30 or 40. Double if they have a bye as well. Two weeks to think about there putrid performance.
Looking at MLB teams that lose by 10 or more runs. How often does this happen over the course of a season?
Most bettors psychologically don't want to back the bad team and think they stink. Most professional teams don't like to be embarrassed and will be extra-motivated next time out.
Also looking at betting on teams that get shutout.
That's the theory anyway.
