Apparently ESPN is doing their player rankings again this offseason and they have Sullinger in at #247. That puts him just behind Gerald Green and ahead of guys like James Jones and Rashard Lewis, not to mention several rookies that were picked ahead of him.
Other Celtics we've seen so far: Keyon Dooling (300), Chris Wilcox (340), Fab Melo (389), Jason Collins (391), and Kris Joseph (467). Boston should have eight players in the top 200 in Rajon Rondo, Avery Bradley, Courtney Lee, Jason Terry, Paul Pierce, Jeff Green, Brandon Bass, and Kevin Garnett.
I guess none of this is too surprising. You can feel free to quibble with the rankings all you want, but allow me to point out that last year they had Troy Murphy ranked 130 spots ahead of Avery Bradley. So, you know, things change. A bit.
