He adapted to Cam. Josh adjusted for Mac. You might be over stating the differences between EP and WC. It is not calculus.
I love Maye, but he is reckless at times. Too many bad passes, too many dangerous runs. Maye is young and needs "in-game" discipline. I think Josh can do that like he did with Mac. Josh can slow down the game for Maye. For Drake over the next 2 years, I think the QB in-game management is more important than the offensive scheme. Maye can identify the Mike, read the defense, and set the offense, he is a smart guy, he can handle that easily. Maye's downfall is his passion that leads to some crazy execution. Josh will be in Maye's ear continually to keep Maye's head in the game.
Josh is coming off failure in LV, is well rested, and has Vrabel taking the pressure off him. I think Josh will get a lot more out of Drake.
