Nelson possesses a thick, burly frame, intimidating power and a burning desire to bury the man across from him. He has great size and exceptional potential as a run blocker. He's able to unlock his hips into contact and uproot defenders, creating massive running lanes. Nelson has been well-schooled by Notre Dame offensive line coach Harry Hiestand. The way he works with left tackle Mike McGlinchey on combo blocks and double teams is a sight to behold. There are times he will get out of position as a pass protector and he has had some injury issues in the past. However, his size, power, play demeanor and ability to dominate in the running game make him my top offensive lineman to watch heading into the season.
