You're dead on about that, but football is also a game of inches, angles and milliseconds. Remember the FSU kid outrunning the angle on the kick return td? There's no substitute for speed. JT won't be called on in power situation, but his stature can be an asset in short yardage nonetheless. He can get the corner on the triple option when the D sells out on the dive or he can find a small crease at the LOS and fit in their with his quickness. One thing that impresses me about him is his agility/footwork in tight spaces, especially at and around the LOS.
