its not the weight its the body type. Look at football players. 285 is on the light side if your an offensive lineman or defensive end. Those guys are the balanced combo of speed and power. Now those guys are 6'0 to 6'4. Curry is 6'11. 285 on Curry and he would be scrawny. He's not Tyson Chandler... he doesnt have that body type. Never did. He's big boy and thats fine. So long as he's not a big fat boy.
A couple rounds of HGH/Decca should get him going
