The bottom line in coaching is how you learn to make the right adjustments. He spent years working for a master of that art. He should be fine. if he struggles one can always bring in a wise old head as an assistant to help himYep. He won the offseason. Roster reconstruction has been impressive.
If he can coach [and in fairness, there's no way to know at this point], he'll be a great hire.
Should not need it but we will see when the bright lights are on him.
