#1) QD and TG are two different styles of quarterback so IMO yes QD is no TG, but only due to style of play.
They are not the same because TG is better . He passes just as well and is way more athletic.
#2) The only way I see us taking TG's commitment is if we have scholarships to blow in Feb. next year. We are going to have a small recruiting class compared to normal and we have a lot of other positions that need attention as well (OL, DL, LB, etc.).
So they wouldn't make room for the guy who is their number one target and a top 10 player? They took QD in case we don't get Tg. Not instead.
#3) This goes along with #2. We have 2 QB's committed already. Jennings and Dormady. Two different styles from what I have seen. No need for a 3rd QB. Plus, Jennings is working his tail off to get better with his passing mechanics. That shows leadership to me as well.
You can never have too much competition. Let all three fight it out and the worst transfers. If QD is the guy he will win and the other two transfer or move positions.
#4) This one is more speculation on my part, but I have noticed that CBJ does not put up with crap off the field. If I remember correctly (and I apologize if I am wrong), but TG got himself into some hot mess with his HS team and got kicked off. Not the personality type CBJ would want on his team nor does it parallel the personalities of the players he has recruited so far.
