Just watched 23 minutes of footage of the 62 finals game 7. The one that has been held up here as Russell's signature game, at least offensively. Now, I'm not claiming to have the knowledge that Joker gleaned from watching multiple games in person, but just my opinion based on a few minutes of action....
Russell's offensive game is embryonic. Clearly, he can't shoot and has very limited post moves. He is sort of the anti Kevin McHale. He is playing against one of those 6' 7" unathletic white guys I mentioned in a previous post (OK, maybe he is 6' 8").
Russell was fantastically athletic for his time--he would be one of the most athletic big men even today, 50 years later. I think, as someone else mentioned, his 1960s self would step right in and be a DeAndre Jordan type force on defense in today's NBA. Offensively, I think he would be similar too (maybe a little better), although he was certainly a better passer than Jordan.
The Celtics team overall is so much better than the Lakers its not even funny. No wonder they won so many championships. To attribute all of that to Russell is nonsense. Russell, Sanders and Sam Jones are all tremendous athletes who wouldn't look out of place in today's NBA. Cousy is a marvel, like Steve Nash on speed. Baylor and West are certainly legit, but the rest of the Lakers are a sad bunch.
