As of August 24th, 2010 our center rotation for the upcoming season is Al Jefferson (who is a PF) and Mehmet Okur (a converted PF coming off of what used to be a career ending injury). These two guys (even at 100% strength) -- neither of them a 7 footer -- aren't going to help improve the Jazz interior defense. We have little money left, and I don't expect the Jazz to make another trade this summer. Filling out this need (at the very least, another warm body) will most likely be achieved through free agency. According to NBA.com's 2010 Free Agent Tracker at the start of free agency there were 31 centers on the table. (17 more if you click on Forward-Center) The people remaining after nearly 2 months of free agency are: Earl Barron, Josh Boone, Primoz Brezec, Jarron Collins, Francisco Elson, Kyrylo Fesenko, Chris Hunter, Steven Hunter, Ian Mahinmi, Sean Marks, D.J. Mbenga, Randolph Morris, Rasho Nesterovic, Fabricio Oberto, Patrick O'Bryant, Oleksiy Pecherov (who just injured his shooting hand), Brian Skinner, Joe Smith, and Etan Thomas.
Very few of those guys are 7 foot, and even fewer are good players. Any list where Jarron Collins starts to look half-bad (as opposed to his regular full-awful) is a bad list.
Where do the Jazz turn? Feel free to elaborate in the comments section. This data is important for me, so I can finish my epic 5000+ word tome on the center spot and the Jazz this upcoming season.
