I agree with all the preseason comments, it really isn't a good measure. It's almost as bad as all the sports writers talking about Adam Morrison during summer league. These are glorified pickup games. If you watched any 4th quarter of any Celtics preseason game you were basically watching bad conference college ball.
As far as E'twaun goes, I think he was a good 3rd string guard, probably never a starter. He's not an efficient scorer which is one of the reasons he might thrive on a rebuilding team. E'Twaun is averaging 10.5 shots in those 8 games and getting about 11.38 ppg.
http://www.82games.com/random10.htmI know that article is old but it's a good indicator of what I'm talking about. E'Twaun is at the bottom of the league with that ratio and he's playing against preseason talent. If he plays against 2nd string talent he's looking at (in his division):
WSH: Crawford/Price
ORL: Reddick/Smith
MIA: Allen/Cole
CHA: Walker/Henderson
ATL: Williams/Teague
He's in the bottom half of those guys for sure and we got Courtney Lee who is a better guard than any of those guys listed except maybe Ray Allen and (the potential that is) Kemba Walker.
Danny worked miracles getting the PurDuo out of here and bringing in Courtney Lee. Easily the steal of the off-season.
