Some guys clearly have a visible "it" factor. Dan O had the arm strength and accuracy. The ball really came out of Tim Boyles hand enough so that l though he'd be great. Cochran could see the field and make quick good decisions with the ball and Pindell had some serious quickness. Each of them had something that you could say, "this guys might be really good". So far with ZT his "it" factor might be his leadership.
As a fan, I'm hoping his "it" factor might give him the drive to improve in some of the other areas. "It's not what you got, but what you make of it", said someone. There were games this year where maybe a handful of passes went beyond the LOS. They clearly tried to manage the game and protect the football. That won't get it done.
So, as said by biz and others the QB play needs to improve - a lot. I'm confident ZT will make strides but how big in one year? The scenario expecting is that through improved health (Tyler Phommachanh, Roberson and Mullen), incoming freshman (MacDonald looks really good it me), a transfer or ZT improvement, the level of play will be much better next year.
