Nichols, Fair, Warrick all skinny minis of the 2000s
Not so much Fair, but yes on the others and I am sure there are others over the years. Louis Orr was the prototype. Some of these kids were skilled enough to play right away despite being thin -- Orr is an example. Others weren't players until they did a lot of work on S&C -- Rautins.
I can't see BJ defending anyone (playing the back of the zone in ACC play) until he adds muscle.
