I have him 5th on my ranking right behind Tiki. I'm worried about SJax getting injured with his upright smashmouth running style.
Coach L will run more than Martz but tends to do the opposite of Martz and throw inside the 5 which will affect his td's. I feel you have 4-5 rb's after LJ, LT2, SA, and Tiki that are extremly close. And the only reason I have Tiki above him is the # of catches but only by a very small margin.
