He's not the franchise changer like those guys but you can't argue with almost 95% of NBA champions being built around two stars usually (with the exception of Jordan/Pippen) one of those two stars is a post threat.
Just to get it out of the way now before someone says: "YOU IDIOT LOOK AT DA PISTONS" the 2004 Pistons were an anomaly. If you want to look at the 1 in 50 that did it a different way to show how it should be done, more power to you.
Dallas didn't have a traditional big that could dominate in the low post....neither will Miami this year when they win, although Bosh has his moments and LeBron will occasionaly out athlete/strength a weaker perimeter player. However, I see what you are saing, but 95% of NBA champions were that way because there was a dominant franchise changing big. I get what you are saying and historically it makes perfect sense, but IMO today's league is different and Howard isn't that type of player. Don't get me wrong he's good and a top 5 player in the league, but his skillet isn't that of a frachise changing big. As I said though with Howard the Bulls are closer to winning championship than what they are with Noah, Deng, etc
