I dont think the offense they run in NY is good for Zach. Most young QB's will mentally struggle playing in NY with all the media attention and the bipolar fan base.
I think Zach has the physical tools to be a good QB but to much noise playing in NY to keep your head on straight.

Not sure this benching is the Jets giving up on Zach, but more of a sit back, watch and clear your head. Maybe it will light a fire under him or maybe it wont.
