Zach tries to 'take it on his shoulders' and make plays that shouldn't be made.
And I'm sorry, but because Romney plays like he does, he's made throws in tight spots, down the sidelines, etc. that I've really yet to see Zach pull off.
So, I'm okay with letting him take over again at QB1, but Zach should be watching lots of film from the last few weeks on Hall and Romney, because we didn't miss him like we should have.
