Obviously I did not watch all three games in total but I watched enough to see Richards is very solid against good college DEs. Some things I noticed:
He looks the part. He has good size and moves like an NFL tackle.
He stays on his blocks. He is not a 1 punch and let up blocker. He gets on his guy and stays on him. It doesn't always look pretty but the attitude is there. Is Richards the next Terence Steele?
