Thinking about Iverson in the top 30, it's not that far fetched. Off the top of my head, I would definitely put the following ahead of him: Russell, Jordan, Bird, Magic, Kareem, Wilt, Duncan, Hakeem, Shaq, Oscar, Kobe, West, Karl Malone, Moses, Dr. J, Pettit, Cousy, Baylor, Hondo, Barkley, Robinson, Stockton, KG, Isaiah, Pippen, Rick Barry, George Mikan. That's 27. There are a lot who are arguably better than Iverson, but you could argue Iverson, an MVP and 10 time All Star, and/or Nash, a 2 time MVP and 6 time All Star, were better NBA players than these guys: Cowens, McHale, Payton, Dolph Schayes, Kidd, Willis Reed, Gervin, Tiny, Ewing, Sam Jones, Sharman, Walt Frazier, Walton, Maravich, Parish.
That's 44 guys total. A lot of guys on that latter list would probably have been better if not for injury shortened or plagued careers (McHale, Reed, Cowens, Tiny to an extent) but Iverson gutted out a lot of amazing years in the NBA. I'll always have a ton of respect for what he did in this league, and I don't think it's crazy to think he's one of the best 30 ever. He's certainly one of the best of his generation. That he's now too old and was blamed for Detroit's collapse - much of which can in fact be attributed to a bad coach, Sheed not showing up last year, Rip missing long stretches and not accepting a bench role, and the Pistons forcing a non point guard (Stuckey) to handle the ball all the time - doesn't change that he was a phenomenal talent for a long time.
And I agree that Billups saving Denver and Iverson inhibiting the Nuggets is garbage. Denver won 4 more games with Billups in 09 than with Iverson in 08. Just so happens that it switched them from an 8 seed to a 2 seed. Not surprising considering the West as a whole was far inferior in 08-09 than it was in 07-08 with huge dropoffs from the Suns, Spurs, Hornets and Jazz and improvement only really from the Blazers. The Nuggets had a perfect storm this year (and blew it by the way). Billups has been an underrated player, and that team needed a point guard, but linking solely Billups and Iverson to the changes in fortune of Detroit and Denver is a bit short-sighted considering all that went right for Denver and all that went wrong for Detroit.
I agree with the majority of Simmons' sentiments. I like the Wallace move a lot more than he does (although if it changes from Wallace replacing Powe, Scalabrine and Moore to Wallace replacing Powe, Scalabrine, Moore and Davis, that changes things a lot) but a lot of his comments are spot on. And the fact that the Celtics are still short a real backup 3, again, I agree with.
