The thing that stands out to me about JT is he needs a "clean" pocket in order to pass because he has to set his feet in order to get power behind his throws. Vad could throw the ball flat footed off his back feet (a terrible no no in the passing world) about 40-50 yards down field...which was not always a good thing because he was overly confident in his arm, and he would sometimes force passes with bad consequences. The point is, it takes a strong arm to generate that kind of power off your back foot...if you don't believe me, pick up a football and try throwing off your back foot.
"The hit" against Miami was a good illustration of how JT needs a clean pocket and has to set his feet to make a throw. JT gets clobbered either way, but if he didn't need to set his feet he gets the pass off to the flats where there was a receiver open. There was one throw on his HS tape where he runs to his right into open space and delivers a ball 30 yards down field, but that was to his right side and his mechanics on the run was perfect. There was also quite a few instance in his tape where if he would just stepped up, there was receiver wide open. Instead, he's distracted by the rusher and starts to scramble outside of the pocket. He's gotten better with keeping his eyes down field the few times I've seen him in scrimmages so maybe that translates over to games.
I think JT exhibits better anticipation and a little better accuracy in his HS tape than Vad did. A lot of Vad's passes were BOMBs down the field. JT had quite a few passes that he was able to either thread or deliver between the CB and the safety. Looks easy, but you have to able to anticipate separation, and deliver it in a small window. GT has a lot of those kinds of passes to the ABs, so that's really promising.
My conclusion is JT, like every other QB we've had, will get better at passing. His arm strength is better than average for what we do in our offense. We don't throw a lot of deep outs to the far sideline, or deep comebacks down the seams, so really having a howitzer isn't needed. For our offense and what we do in passing, JT's arm strength is more than strong enough. I'm more worried about accuracy, anticipation of where our receivers should be (that's on JT AND our receivers), and reading coverages versus our concepts. JT has exhibited the first one, the other two we'll find out over time.
