Burrow didn't wait. Hurts didn't wait. I'm not suggesting HB is near that level but Taulia didn't wait either, despite dropping several notches from Bama.
Obviously, I wish Bailey would wait but let's say we're 7-5, Milton gets 80% of the snaps, Bailey and Hooker split the 20% relatively evenly, mostly garbage time. Milton won't declare for the NFL unless he has a breakout game vs AL, GA or somebody that matters. Nobody cares if he tosses 7 TDs vs Tennessee Tech.
Next year, similar, maybe 8-4, even 9-3, and Milton has gotten all the "Heupel hype" he can get and declares. Is HB in a fight with Tayven? And who was that new QB Heupel pulled out of the portal at the end of last season.....
I'm not sure college football is a "sit and learn" game beyond one year anymore. Do we think talent like Jackson sits behind Milton one year then Bailey one or two years?
I don't know the future of college football but seriously good QB talent seems to be waiting a year.
