The size thing is a bizzarre hypothetical, If Burrell was 5'10 instead of 6'5 would he have been a D1 level athlete in any sport? I never understand it when people do this with players, people say Shabazz could have been a top 5 pick if he was 6'4, well he would also probably be a completely different player. I judge players on what their actual size, speed and strength is. I think Shaq is a freak of an athlete because he was 7'1 350 lbs. And had amazing agilty and body control for his size. If he had the same agility and body control at 6'1, I wouldn't be too impressed. My guess there has been plenty of freak athletes throughout the nba and nfl over the years who could have played multiple sports at the highest levels but if a kid thinks he has a good chance at a professional career in a sport he's almost always going to totally focus on that sports and forget about the other sports.
