I whole heartedly disagree. Football is not basketball. look around at the teams that hit the portal heavily and the teams that added kids here and there. The top 10 has many more of the latter than the former. to build a program, you have to have kids in the program more than a year. An NFL team could theoretically sign half the roster to one year contracts, but they choose not to for continuity reasons. It’s not a program if the roster turns over quickly.
I think almost everyone agrees college football in general is not as good the last couple of years vs the 8-9 years prior. the big culprit , IMO , is the transfer portal.
