The way I see it... The Jets have 2 quality TE's that, have been there longer and know the system better than Zach... Baker and Ryan have played very well....
The Jets also only dress 2 true TE's... the long snapper being the 3ed guy... they like to dress 2 Fullbacks, that contibute a lot on Special Teams ....
Zach was just there to insure against an injury to the top 2 guys... they needed an OLine slot... Zach was expendable...
That's life in the NFL...
Hopefully he will land in a decent situation... if not, he has to look to getting a decent shot somewhere in the off season...
There are a LOT of guys busting their butts to get a few slots in the NFL... that's the reality of the situation...
