Since it seems more and more unlikely that this team is not going to be able to win a ton of games after the trades of Green, Wright and Rondo I am closely following the other seemingly lottery bound teams as their play really has about the same impact on lottery results as our own.
The Dregs:
76ers - They have been a bit more frisky the last few weeks and are up to 7 wins. However, they are also the most blatant tanker and their GM would shut down or trade any productive player if they are start to win many games.
Knicks - They were down 14-0 to start the game against the Bucks in London and never got back into it. The question isn't whether they will win more games than the celtics, but when they will next win a game at this point.
Timberwolves - Wiggins looks awesome, but they are still losing nearly every game and looking to trade off one of their productive NBA level players in Young. May get Pek and Martin back but still really locked in to bottom 3.
Throwing in the towel (and bad news for Celtics):
Lakers - They are continually competitive in games but are also accomplishing their goals of losing. With today's story that Kobe would accept being held out of games after already being on a 32 minute limit the tanking remains really strong. If you look at the guys they are playing when Kobe doesn't (Boozer, Lin, Wesley Johnson, Nick Young (playing horrible), Ronnie Price, Tarik Black, Jordan Hill) this team is a lot less talented than Celtics and with much less prospects.
Playing Good (and good news for Celtics)
Denver
Detroit
Orlando
All these teams are playing a lot better at the moment. Despite having the best record of the 3 Denver would seem to be the scariest tank candidate. For one, they play in the west where wins are harder. Second they could very well sell off a ton of veterans if they stay on outside of playoffs
Who Knows:
Charlotte: Jefferson hurt, maybe trading Stephenson. Not sure what they are trying to do.
Utah: Lots of talent, but maybe just too tough a schedule in the West. Could be "battling" the celtics for wins and losses all season
Brooklyn - If they trade Lopez for Perk and Lamb they are definitely not trying to win this year. Deron is extremely gimpy and horrible when he plays. What a mess of an organization.
