I just see Bird as one of the if not the greatest SF to play the game. His court vision, smarts and pure killer instinct are just unparalleled. Imagine what he could do in Lebron's body. Now imagine what Lebron would do in Bird's. I saw you picked Lebron over him for you Mt Rushmore. What's your justification? One MVP and a few all-NBA selections more? I also believe Bird played in a much more competitive period in the NBA than LBJ.
Easy (green glasses off): Bird, Russell, MJ, WiltSeems super green to me , but interesting list. What makes you think that Bird and Wilt are in the top 4?
As for Wilt, it's just his monster stats, freak athleticism and durability (averaging 48.5 min per game, just absurd).
My justification is that LeBron's prime is as long as Bird's career, and that's not even counting LeBron's first 5 seasons in the league - he tacks on 2 seasons that have an outside argument for MVP, an All-NBA season and an All-Star year in that 5 year span. And I don't think that a more competitive league would boost Bird's accomplishments to the point that 8 prime Bird seasons+3 post-prime years is more valuable than 4 years of good pre-peak LeBron+11 seasons of prime LeBron, especially when Bird didn't clearly have a better peak (I'd go so far as to argue that LeBron trumps Bird in that category as well).
