Mott the Hoople
Sweet Jane
A cousin of mine who was all of 5'6" tall and 150 lbs soaking wet played nose gaurd on his high school football team. I saw him several times play against Centers who were in the 280 to 300 lb range. My cousin would run in low and take his legs out and the middle LB would run over the top of the fallen center. They got a lot of sacks and stopped a lot of runs doing that and it was hillarous to watch.That is exactly where he was used. Unfortunately he can't get the ball, but having an extra blocker of that size and mobility is enough.
