Paul Pierce is very much like the Ginobili of this conference.
While everyone loves to say that the Spurs *are balanced*, etc, etc, all one really needs to do is look at Manu's health. As soon as his ankle or hamstring is sore/pulled, the Spurs run is over. The difference between them winning it all and being ousted by the Lakers or the Mavs is one player, who can put it on his back and deliver.
For us, we have Paul Pierce. And for the most part, I would love to have seen him on a team, like the Spurs, so that he could prove my point. Instead, he was carrying the Cs, for many seasons with a faux point forward, Walker, instead of someone, who can rebound, play paint defense, and take good shots.
Someone once said that if we'd switched KG with Carlos Boozer, during that 2008 year, that the Jazz immediately wins the title. For this, I disagree, as the Jazz were not a defensive-minded team, unlike Thib's C's. I think that Boozer plays in the middle and does as fine a job as anyone else, guarding the paint and scoring down low, but this time side-by-side with enforcer Perkins, prior to his recent follies in Chicago. I like Boozer/Perks up front, it definitely gives PP and Ray Ray, a lot to work with. And yes, we'll be hearing all kinds of stories of Carlos not being clutch, however, in this alternate scenario, since he is playing down low, it really wouldn't be all that necessary.
In this arrangement, Pierce can still lead the C's to a title as long as Carlos brings his 'A' game to the series and doesn't mail it in due to personal issues. But he doesn't need to overachieve, which we clearly haven't seen from KG either.
