I was thinking about this last night watching Gerald Wallace and Jamal Crawford for Portland -- there are a lot of NBA players who do their jobs very well but aren't necessarily "known" or appreciated the way they should be. Who's on your list?
I'd also contribute:
Tony Allen
Marcin Gortat
Ryan Anderson
Tyson Chandler
Andrea Bagnani
Kyle Lowry
Kyrie Irving (just because he isn't a bona fide star yet)
