It's not so much being low but his competition. Would have preferred he go back for another year, but he's going high 1st round so he's made the right choice. He's got like rich-kid character concerns but there doesn't seem to be evidence that it's made him a bad teammate, I'd trust that Joe Douglas did his homework
Yes that's also the first impression that I got from Zach based on his look. A rich, douche with blonde hair and tan. I was like nope!
Then you look at the tape and you say ok that is good but he played against shitty teams, so what's the deal?
Then I started to listen to him and people that have been around him and I understand that I was totaly wrong on him. He is obessed on his craft he spent all of last summer watching tapes, changing his arm mechanic/motion and analyze where he could improve with a private coach while doing Door Dashing to be able to afford him. He is way more humble and willing to work than his look would indicate. He has the great trait you want from a QB which are contant improvement and self assessment/awareness. I could go on and on but things you can see on film that he improved from last year are incredible. From his arm angle throws, off platform mechanic, his eyes movement, his anticipation, his touch and more importantly his ball retention.
He has been labelled a tape freak, always analyzing other QBs and where he can improve. Anyway I understood the hype after that.
