Any chance Duncan could be that reason the Spurs never missed the playoffs since he arrived?
The point that some are making is that Duncan has always had a playoff level lineup around him. We don't know if Timmy could drag the likes of Smush Parker and Kwame Brown to the playoffs because he never had to.
We do know that Kobe could drag the likes of Smush Parker and Kwame Brown to the playoffs because he did so twice.
Could Timmy have done that? Probably. Could he have done what Kobe couldn't and get that same lineup past the 1st round? Maybe. But we'll never know, because he never had to. That's not a knock on Timmy, but more praise for how well the Spurs have done in keeping a playoff caliber lineup together.
