you know if you think about duncan as a center, he's one of the better centers in the league. if you think about him a forward, he's pretty damn mediocre.
Yeah, well, I kind of see a closer resemblence between the PF and C positions than I do between the PF and SF ones. But I see where you are coming from with that.
Duncan's role offensively as a center is limited, but he still brings more than 98% of other NBA centers from an offensive stand-point when he is actually out there on the floor. Offensively, the two positions are very interchangeable.
Love is a guy who really gets outmatched by nearly every other starting PF in the NBA when it comes to how many points he is allowing his man to score versus how many they are allowing him to score. But, of course, that would be doing a discredit to Love because he makes up for a lot of his mediocre offensive game with his offensive rebounding. The reason his FG% is as close to 50% as it is, is because of his near 5.0 offensive boards per game... he gets about 3 or 4 baskets per game that way.
I still see Duncan as a dominant force when he's out there on the floor. Love is getting better but he's not the impact player Duncan is. He does it all very well. Love has been known for 'doing it all' in his UCLA days, but he does not utilize them as well / play with a purpose like TD does.
