GREAT POST! Wish I could give you a 5* like.
I think Heupel is better at building a good, sustainable culture. There seems to be very good discipline. Not just the punishment kind but emphasizing behaviors and decision making that lead to maximizing success. It has continued to develop and grow. Keyton mentioned that the WRs themselves set a goal to catch 20,000 balls from the jugs over the summer. The reports of a standard being set that guys like #9 are just now really understanding is another indication that the bar for effort, values, commitment, behavior, etc is being set really high.
Could that be a product of Heupel's experience as a player?
