I'm not sure how overrated the talent level is, however I do know that this team achieved a certain level of mediocrity this season. And it doesn't matter much about injuries and chemistry. I've just felt all along that this team had declined to a level where they weren't bad enough to miss the playoffs, but they were not good enough to make a deep playoff run either.
The issue with the lack of size and length is very disconcerting because, as I said in another thread, it's not like Dirk just emerged as a superstar player. He's been a bad matchup for this team for several years. Factor in the length that the Fakers and Blazers have and it's quite mind-boggling why the FO hasn't properly addressed this roster deficiency. Meanwhile, Pop insists on going into battle with an over-the-hill (McDyess) PF and a slow, inferior, 3-pointer shooter (Bonner), who both masquerade as 5's, in a smaller and slower frontline.
