Center - Shaq, Yao, Big Z. PF - Duncan, B.Wallace, Webber. SF - Garnett, Dirk, Peja. SG - TMac, Kobe, Pierce. PG - Kidd, Payton, Nash. Yes, some of these guys are out of position according to their Starting Lineups, but if they were put on a dream team these would definitely be the positions they play
C: Shaq, Nowitzki, B Miller PF: Duncan, Garnett, B Wallace SF: Marion, Stojakovic, Mashburn SG: McGrady, Bryant, Iverson PG: Kidd, Francis, Nash * Nowitzki is playing Center this season (and has played plenty in his career), so he qualifies as a C! ** Yao SHOULD go past Miller and become the 3rd best Center in the league this year (and the 2nd best 'true' center), but he's got to start showing that he's better than Miller before he gets ranked there (otherwise you could argue that Lebron should be in the top 3 SF's because he's talented...)
I think he plays both - he and Jeff Foster start as the 2 big men for the Pacers, Foster normally pulls the opposition center as a matchup.
C: Yao, Shaq, & Ilguaskas (O'neal doesn't count) PF: Duncan, Dirk, Webber SF: Pierce, KG, Rashard SG: Kobe, T-Mac, AI PG: JKidd, Payton, Nash (time for Franchise to step up)
