Perspective from Pistons fan:
I personally think (objectively of course) that an Indy-Spurs match-up would be extremely compe ive. I think there is a lot of merit to the claim that Artest would have a good mismatch, even against Bowen. Artest has about 50-60 lbs on Bruce. And, as good a perimeter defender Bowen is, I think Artest would be effective backing Bruce down.
As unstoppably quick Tony Parker would be against Tinsley, I think Tinsley would have similar advantages with his size and bulk. Tinsley is somewhat similar to Chauncey Billups in that he has the size, bulk, and height to back-down smaller guards as well. If Tinsley is shooting well, it would completely open up the rest of his game against Parker. I don't think it's clear that either point guard would dominate this match-up, and it would be a game-by-game performance.
Duncan is the best player in the league. There are other big men in the league that are more talented or more athletic. But, there is no better combination of size, athleticism, IQ, polished skill set, leadership, winning at ude, and hard work in the league. Jermaine O'Neal may be able to keep things close statistically. But, I think Duncan is the type of player who makes "winning plays," even if it's not scoring or rebounding. It might be an altered shot or a hard pick to free open a teammate. The distinction is that Tim Duncan knows how to win. He's experienced his share of losing as well, so he knows adversity. This match-up is not important merely for the stats comparison. It's integral to their respective teams winning despite the statistical comparisons. And, that's why Duncan and the Spurs would have the advantage.
I also think the Spurs have the better bench, more proven, more experienced.
I don't think it's right that a lot of Spurs fans don't think it would even be a contest. I think it would be closer than the majority of Spurs fans believe. But, bottom line is I still think the Spurs would prevail.
Anyway ... doesn't matter much. I still think the Detroit Pistons are the team to beat in the East.
