You are like the bitchy wife who nags her husband about something he said YEARS ago. Good one...
They're not similar at all except for weight. Again, I don't know why you're getting so hung up on size when we're talking about a uniquely gifted player. What's your point with the weight thing anyway? That they're too slow, not as explosive? I just gave you an example of a 275 pound guy with Tamba Hali. He's way slower, less explosive, weaker, less talented, and less productive than Mario Williams, and he made the transition, but Mario Williams can't because he weighs more than 280 pounds? That argument fucking sucks.
