For the College Football in the know crowd:
How can the NFL make a full season with 53+ but college struggles with depth when they have fewer games and more players than the NFL?
Because the NFL is the cream skimmed from 15+ college football seasons. They are 53 each Sunday* but there are also practice squads and a pool of emergency guys more or less on call if needed.
But relatively speaking, depth remains an issue especially when injuries mount up.
* and only 32 teams skimming from 130 FBS teams plus whatever they take from FCS and other places. Rough numbers over 15 years, that’s over 165,000 players vying to fill 2,000 roster spots. Even if you take the average NFL career is 3.3 years, round it up to 4 years that’s roughly 42,000 players to fill those spots. So less than 5% of FBS players even get on a roster at all.
I’m just goofing around with my calculator, but when UM3 talked about looking for the 1% of 1% to compete for championships, he wasn’t exaggerating. A number of articles say 6.5% play in college at all, and just 1.6% of college players get drafted. But that’s probably including all college players down to D3 & NAIA.
