When your job is football and you practice nearly everyday, you will have some off practices. If you coach jumps in your face everytime you do, you lose respect for him in that regard, as it's not possible for most players to practice perfect everyday.
It's amazing to me that you think that Wanny jumping in McMike's grill would make him a better coach. Half these players are so immature that they can't handle anythnig other than a pat on the back. They do not live in the real world and most of them do not have the mental toughness you'd think they have.
Wanny will appear to be a much better coach when our players start making the routine plays at their position.
