re: Why is it so much more difficult to go undefeated in CFB today than in the past?

Yeah. Not sure how the draft was prior, but that could make a ton of sense if that's the case.

Even though some teams may have more talent, a lot of the talent may be leaving earlier.. and less experience could catch up to a team.. even versus a lesser talented team who may have much more experience playing together.

Athletes today may be getting better all around.. and dispersing all over.. coaching continues to get more creative all the time.

Idk, pretty interesting though.
