just my opinion, but I think as a RS sophomore, first-year starter, VL did well enough. I think had Vad stayed and put his heart into this system, we would have seen the same progression from SO to JR to SR that we saw with Josh and Tevin. Since he's not going to be here for his JR and SR years, we get to start over at the RS SO, first-year starter again. I expect to see the same level of development and growth with JT that we saw with the first two guys.Nesbitt and Washington had different styles. The offense was tweaked to fit their strengths.
Our coaches never could figure out what Vad's strengths were, or they never developed Vad's weaknesses. Short of that, if they realized he didn't "fit" the offense, they should have started to play JT more...as many on here have pointed out. Why invest valuable reps on a QB if his longterm potential in this offense was limited? THAT half is on the coaches.
Vad was responsible for the execution. The talent and athleticism was there. 2012 was a great example of what he could do. 2013 Vad, for various reasons, just didn't work out.
To say it's 90% on Vad is pretty weak, and absolving the staff from responsibility.
