He is trying to find the seam to burst through with his acceleration rather than sprinting with his head down right from start. Not sure what is "right" strategy, but he has been doing the kick return thing since long into college right? Let's give him benefit of doubt. He did do his patented zoom a couple of times bursting through into a lane, which he would not have found by sprinting full out from start.
To me, Jones looks a tad heavier than last year. He looks like the size of an everydown back, but seems to get dinged a lot. Figured he's score on that long run, but he got run down at end. He seems far more muscular than when he was drafted, which is ok if he keeps up that ypc.
