there's more to this than number. Our 3 starters last season (parker, marion, JO) are still starters, and on better teams this time around. Parker and marion should have trended down just because they are old, and are on teams with more scoring firepower (except for miami). Kapono, moon and the others are really doing the same thing, but getting fewer minutes (since our team last year wasn't deep, so we had to use them more than they deserved).
Too bad you didn't include TJ (9/4 with 38% FG as a starter for Indiana ...), even though he wasn't here last season, he's still missed by some I'm sure ...
