Posted this in college forum, but makes sense here. Bad beats I believe are a real thing, but consider:
Last week 25 out of the 55 "main board" college football games had final scores that fell within a TD of the closing line. So, nearly 50% of games are decided ATS by one score or less, which, as we know, can a lot of times come in the form of pick sixes at the end of games, turnovers, fumbles, missed or made FG, or just plain goofy stuff like Hail Mary hook and ladders that shouldn't have even been plays in the first place. As the volume of games on your card gets higher, the more likely these situations will affect you, good and bad. The goal is to find as many games (winning sides of course) that fall out in that other 50% - games that are never in doubt, and where one bad bounce here or there makes no difference ATS.
The worst thing you could do is to change your strategy, either in size of wager or number of wagers, because of these things.
