Are huge upsets more probable in college football or the NFL?

NFL easy.

If you're asking this question, you probably don't watch either.

Upsets in professional sports are much more common.

NFL, but for that reason they really arent upsets in the way they are in college.....anyone can win on any given Sunday in the NFL

NFL

It's kind of a difficult question. The worst NFL team is much closer in talent to the best than the worst college team is to the best, because there are only 32 NFL teams, there's a salary cap, even the worst team has elite talent, etc. So in that sense, it's much more likely that a bad team like the Jaguars would beat the Seahawks than a team like Georgia Southern would beat Florida State.

But if you look at it a different way, I think there are more variables in college football. Players have to deal with classes/tests and less time for practice. They might be having girlfriend problems. Plus, they are more likely to buy into the hype they're getting and are more vulnerable to pressure and mistakes than pros. Additionally, an underdog team in college, I think, is more likely to have an "us against the world" mindset, be impacted (positively) by emotions and really be motivated to pull off an upset. I don't think this is as likely in the NFL, where the preparation and overall lifestyle of the players is more professional and less sporadic. So I think in the NFL, both teams are more likely to play their 'B' games all the time. In college, a great team could play a 'D' game and an underdog could play an 'A' game.

Basically, if a spread in an NFL game is 14 points, and a spread in a college game is 14 points, I think it's much more likely the college game will end with the underdog winning. But of course, 14 is probably close to the largest spread you'll see in an NFL game, while college has games that are much larger.

I don't by upsets in the NFL, anyone can wake up Sunday morning and beat you.

They're all professionals.

do you even watch football bro?

How is this even a question? The NFL only has about 30 teams all filled with the best football players in the world. Sure some teams aren't that good, but it's still made up of professional football players.

The difference in a great NFL team and the worst one is much, much smaller than a top 5 CFB team and one ranked in the 100s.

All the teams in the NFL have professional players, so things are a lot more even. Therefore, the last-place NFL team has a better chance of beating the top team than App State had to beat Michigan. By the same token, an NFL upset isn't as "huge" as it would potentially be in college, so I will say college just because the magnitude of an upset can be greater there.
