The coaching was truly atrocious. The defense was equally bad. BB had a bad week.
Zappe didn't cover himself in glory but he's the guy I want moving forward (and based on how that game finished, I sense that will be the case).
It seems to me Zappe's issue (primarily getting the ball across the LOS on the shorter stuff) is easier to work with/around than Jones' issues, which seem to be rooted in an inability to really feel the pocket and see the field simultaneously.
Play-calls, route-combinations, blocking techniques, little movements in the pocket to create lanes, etc can all help Zappe. If Jones can't consistently feel the pocket and see the field, I don't know how you work around that.
Zappe also has the ability to fit the ball into tight windows that Jones just doesn't.
