Basically any linebacker is bigger than lbj. Clay Matthews is 6'3 255 he is smaller and has weight on bron, the majority of football players are bigger than basketball players its normal. Bron in the nfl, HAHAH. He complains about a little contact in the nba in the nfl he would be worst than tom brady when he just ducks to the ground to avoid contact.
if he had chosen the football route instead of the NBA coming out of high school, i'm sure his physique would look much different. while both sports require working out, the large muscle groups are not worked out the same in the NBA as they are in the NFL.
