Tyson Thompson is not the back Barber is....Thompson hits the hole hard and has speed...he did break a first down outside on Sunday...it wasn't all up the middle.
However, he has shown no moves, broken no tackles...not yet. Barber is slipperier...he slithers through the smallest of holes, knows how to turn his shoulders sideways, has some moves and elusiveness (though not as much as JJ), and he definitely finishes runs...I jumped up and hollared on Sunday when he lowered his shoulder and ran over the defensive guy without going down himself.
Right now JJ is #1, Barber is #2, and Thompson is #3....I don't see it changing anytime soon.
