Winner of the 2011 Jazzfanz mock draft contest
9'3.5'' standing reach does not constitute an undersized center (you don't defend with the top of your head, after all). Aldrich has all the size he needs to be a true 5 in the NBA.
As a person that likes Aldrich, I'll admit there are concerns about him, like any prospect the Jazz will pick #9 (albeit fewer than other prospects I would say). But I agree, size/wingspan isn't even close to a concern for Aldrich. That's actually considered a strength of his.
