Still hard to argue against Bill Russell: 11 NBA championships in 13 seasons, 2 college championships in 3 seasons, 1 Olympic gold in 1 attempt. The stars of that era-- Wilt, Oscar Robertson, Nate Thurmond, Jerry West, Walt Bellamy, Willis Reed, etc.-- all say that Boston could've been beat were it not for Russell. Both guys are great, but it's hard to argue that 7 les in 21 years absolutely beats 11 out of 13.

It's a myth that players were shorter in the past. Today's centers, on average, are actually shorter than in most previous eras.
