I hope it's obvious to most of my fellow VNers that a great number of top collegiate footballers played in small high schools. I watched Joe Young's video a half-dozen times and noticed he's NOT afraid of being tackled. Look again, particularly at frames 7, 9, 12 13, 16, 20 (flat ran over the safety and kept on moving), 22, 24, 25, 27 and 47 where he angled VERY well for leverage and additional yardage. On the rest of those frames he was moving away from would-be tacklers, so his running upright was for sheer speed. I don't know his 40 times, but he certainly looked fast and his instinctiveness for juking away from committed tacklers and knack for running north/south show he's a natural RB and most likely takes well to coaching. Great addition to a team in need of RB depth. His limits? We'll find out soon enough.
