Was that if he gets a 3rd round grade or higher (which he will), that Zach should absolutely go to the NFL after this season. The reason being that the exposure, scrutiny, and focus on Zach won't exceed this year.

The only reason that Zach would stay is if there were significant improvements to be made to his game that staying an extra year he could improve upon. It has nothing to do with the other potential QB's getting drafted this year or next. Zach is on an already record setting pace - what left does he have to prove?
