The current college football environment has increased parity on a lot of fronts.
Jucos, scholarship limits, 5th year free agency, basically any junior projected as a top 90 pick going pro, etc have all increased parity.
I'm of the opinion that there are 3-4 elite coaches that can compete for NC every year. All other programs will when they have an elite qb and chips fall in place. BK is within a small margin of error in the same ability zone as every other of the top 25 coaches minus the elite guys. If Zaire turns into Cam Newton then BK will likely win a NC.
Les Miles is in the same level of coach as BK. We saw his weaknesses yesterday.
