Not every running QB is a blazer. Actually, a lot of them are tough, big, inside runners with a good feel for going through traffic and lowering their shoulder. That's what we have in Tommy. He won't sprint past safeties certainly, but he certainly ran with authority. I think guys like Tebow, Stanton, Bubba Starling were/are the same way.
It's not the highlight reels that count, it's the every run and read and pitch. I think the bigger worry would be his decision making in the passing game. Particularly if we do a lot of short throwing, which Beck seems to prefer.
This. Tebow, Cam, Vince, big guys who ran with authority, ability to make guys miss and get the tougher yards. Frost, Frasier for NU. Not blazers, but got the tough yards. You throw in a healthy dose of Cross that makes DB's less than willing to come and lay the wood and it opens up lanes for a tough running QB like TA. Martinez was a phenomenal crease runner. I have never seen a quicker straight line guy than Martinez, doubt I ever will. BUT, he had
no ability to make guys miss or steam roll a guy. TA runs angry. Like he has something to prove. If he can make it to the 2nd level, I feel comfortable in his ability to either make a guy miss or truck him. DB's get hit enough, they might come up to support the run, but they will start whiffing to avoid getting hit.
Lean on the running game. Call PA to open the lanes and get them out of the box. If he can get that long ball down, use the speed of Bell and JT to stretch the field to open the box. Allow TA to manage the game and lean on the RB's. Call high percentage passes that he can do in his sleep. If he can't complete them in practice at a high percentage, trash them. 70% or better (for example) keep them.
Bama has made a living with game managing QB's who get the ball to the RB's, have a handful of high yield passes and don't fumble, take a sack or throw many INT's.
