I agree to some extent.
The problem, in my eyes, isn't just with Wade's preception of retaining Garret at what he's costing us. The problem is with the rest of the staff and the players. This starts to make it look more and more obvious that Jason will take over for Wade, possibly within the next year.
Now, all the staff has to wonder who to show the most alligence to. The guy that's running things now or the heir apparent. The same with the players. Wade may see it as undermining his authority, and since he's so laid back, he's probably not going to be able to sit Jason down and say, "Hey, glad you're staying, but this is still my team."
We all liked what Jason did with our offense, although I feel it had as much to do with not having conservative Parcells around than anything else.
