Dude , why are you so stubborn?
Attendance was listed as 36K & change so make that 19K empty seats
Everything you listed above is fixed by better players, specifically better linemen on both sides of the ball.
All Coaches attend the same seminars, learn the same drills & techniques, with the exception of a few Clock Mgmt strategies, Special Teams Decisions, maybe 4th Down calls all coaching is substantially equal to other Coaching, what determines winners and losers is Players, linemen first, then QBs , then DBs, then all the other skill positions.
It is all about the Players, if it was about Coaching, our genius previous HC had 1 month to get ready for Iowa and LSU in those first 2 Bowl Games, but coaching meant nothing while we got smoked by 2 Teams with a lot more Athletes than we had at that time.
Better players solves everything, CFB is nothing like it was 70 yrs when Dodd was the HC.
I wish our Fans (not you OP) would forget bygone Eras and try to understand CFB in 2021.
