jamal lewis is kinda big, powerful rb legs. shannon sharpe was a big dude, had one of the strongest benches in the nfl at one time. priest holmes is kinda jacked, rb style. to was making headlines for his workout ethics and he was/is muscular but wouldn't be considered jacked though. reggie bush is kinda stocky, again a rb so... there are def others, of course linemen. which also brings straham to mind, slimmed down & leaned up this year but has some good arms with the definition nowadays.
