They way I take it, Emery and Trest are sold on him since if in 2-3 years it's decided that Jay didn't work out, then neither did Emery/Trestman; they have idiotically handcuffed themselves to him. George on the other hand might not be so sold on Jay, nor their faith in him, and said "alright, if they want to ride and die with him we'll let them," and had it arranged in a manner so that if need be he can clean house in a couple of years. Which reminds me, what's the cap hit on the third year?
I miss the Trestman that refused to call Jay a franchise QB.
