Filling the Blanks: Post KG-trade
The Celtics currently have 11 men on the roster so they need to add at least two players. With the team almost over the luxury tax line, I'm not sure that the owners will be willing to pay for three spots (and send Brandon Wallace down to the NBDL) so the C's might have to make due with only only two new acquisitions to fill their three needs.
So which need goes overlooked? The Celtics simply can't go into the season without adding a third point guard so that leaves the backup swinman spot and backup big man roles as possible odd men out. Right now, I'd put my money on the center/PF spot being passed over. The thinking will probably be that Perkin/Veal/Powe can handle the center position with Veal/Powe/Big Baby and maybe even Brandon Wallace backing up KG. With the only backups swingmen being Gabe Pruitt, Tony Allen (coming off injury), and Wallace, the C's are in dire need of players who can step up and play some minutes so that Ray Allen and Paul Pierce aren't forced to be on the court 40 minutes a night.
So who's out there? For the point guard slot, I'd look at Charlie Bell as my top choice since he's a combo guard who could backup both guard spots effectively. Unfortunately, he's probably out of our price range so I'd take a look at Eddie House, Darrell Armstrong, Gary Payton, Chucky Atkins, Darrick Martin, Brevin Knight or Mike Wilks. A dark horse that I'd love to invite to camp but whom we probably couldn't risk signing is Dajuan Wagner. If our options are bargain basement, I'd look at Aaron Miles, who played well overseas. The bottom of the barrell would be Royal Ivey, a poor man's Rondo who is solid on defense but has no jumper.
For the swingman spot, the first two names to pop in most people's heads would be Eddie Jones or Ruben Patterson. Patterson is probably a no-go because of his checkered past and the Celtics Code of Conduct. Eddie Jones, however, could be the type of players who goes to a team for the minimum for one last shot at a ring. Also, it would bring some justice to the world, making up at long last for the C's taking Eric Montross over him in the draft. James Posey is another option. Ime Udoka and Matt Barnes are possibilities but the odds of them taking the short money looks slim. Perhaps they agree to a Deshawn Stevenson type one year deal to help raise their stock but we'd probably have to wait until they had no other options to make that happen. Udoka, especially, is unlikely to make that type of deal as he is about to turn 30 in a little over a week and his window for making anything more than the minimum probably closes after this offseason. The cheaper, more likely options would be Devin Brown, DerMarr Johnson, or Derek Anderson.
If the Celtics do opt to sign a big man, the first call would likely be to Dikembe Mutombo. He'd be a great addition to the team but might prefer to stay in Houston. After that, there's Brian Skinner or perhaps Keith Van Horn if he opts to come out of retirement. (Not that he should). Cliff Robinson could be an interesting addition and Bo Outlaw always seems good for six fouls. The bargain basement guy would probably be Jelani McCoy. If the C's opt to go younger, they could look at Alexander Johnson, Justin Williams, Erik Daniels, Noel Felix and old friend Dwayne Jones.
In the end, I think the best case scenario would be Charlie Bell, Ruben Patterson, and Dikembe. But since the odds of that seem to be slimt to none, I'll be happy with Eddie House and Devin Brown (and possibly Brian Skinner if we sign three guys).

10. Stephon Marbury: He's the motor that makes the Knicks run and he's got more talent to deal with this year. Can he run the team so the offense runs fluidly? With age catching up with him, this might be the last chance he has to show off his talents and salvage his reputation.

Thankfully, the Miami Heat made a mistake that I feared the Celtics would, which was signing Smush Parker. While many Celtics fans have been impressed by his dismantling of Delonte West, Parker's defense is overrated. He reaches too much and struggles against quicker guards. His point guard skills aren't very good either and his inability to thrive even in the triangle offense basically tells you everything you need to know. 

Orlando Magic: Guard play, bench depth
Charlotte Bobcats: PG play, young players need to emerge
Indiana Pacers: Three point shooting, guard play
Cleveland Cavaliers: 2nd star, re-signing their free agents
Toronto Raptors: Consistent #2 scorer; Perimeter Defense
New York Knicks: Ball movement, Perimeter shooting, defense.
Boston Celtics: Defense, Point guard
And honestly, it's not an issue that will destroy the NBA either. Many people have been pointing to the Suns-Spurs Game 3 as evidence of Donaghy's influence but many of the bad calls or missed fouls were on Eddie F. Rush. If Eddie F. Rush isn't named as one of Tim Donaghy's co-conspirators does that make things any better? Is it better that the fate of the series was affected by Rush's incompetence than Donaghy's dishonesty? And it's not like anybody thought referees were completely even-handed before this. Rookie calls. Superstar treatment. Home team advantage. Something was ALWAYS affecting how games were being officiated. How many times have you heard someone moan "Oh, that ref is doing the game? We're screwed." Hell, Covers.com has an
F: Brandon Bass
It was the Big Baby show today. Granted, he was working against sub-par talent but he still was very impressive. The Mavericks really have to be wondering why they took Nick Fazekas over him. Gabe Pruitt didn't really stand out much. I think his offensive abilities will be put to better use when he is teamed with someone like Ray Allen. 
This is the fact that Celtics fans and coaches need to embrace. Entering his third year, Gerald hasn't improved dramatically and even his supposed stregths on offense are often undercut by his weaknesses. Putting Gerald on the wing and expecting him to create for himself is a recipe for a turnover. Most drives end before they begin because Green is called for travelling when he tries to make his move. If he gets a step on his man, his sub-par dribbling either leads to a turnover or to the defense easily shifting over to stop him. Once his drives are cut-off, Gerald's unable to find a correct pass and the drive often ends with him forcing a bad pass or an awkward shot. For three years now, we've watched this and crossed our fingers, hoping Gerald will improve these flaws. After three years of mild improvement, I think it's time that we look to change our expectations of Gerald and deal with his shortcomings.
Trade Gerald Green and Brian Scalabrine for Robert Swift 
When it was announced that Sun Yue was going to start at PG, I knew Rondo was going to have a great game. Yue is a talented kid but he's too slow to guard NBA point guards. It's odd that the Lakers drafted him because he's essentially a poor man's Sasha Vujacic (who they don't seem to be overly pleased with). Rondo looked good at the start, taking the ball to the whole and taking advantage of the mismatch. He got a little sloppier as the game wore on but overall it was a nice effort from Rajon.
So basically, the only hope this team has to make even minor changes is via trade. The problem there, of course, is that the Celtics' assets aren't that valuable right now. In order to get a good point guard, the Celtics will likely have to deal Rajon Rondo. Perhaps the C's could acquire a capable backup for less than that but we'd be lucky if an Anthony Johnson-level player came that cheaply. With so many teams looking for backup point guards, it is unlikely to be a buyers market. Gerald Green wouldn't almost certainly have to be dealt to bring in a big man of middling quality.
The Main Target: Zaza Pachulia (A strong defender and a no-nonsense guy, He's not that quick but he's probably the best we can afford. Pachulia might be on the block now that the Hawks have Horford and Shelden Williams on the roster. He's good not great and might not cost too much to acquire.)
The Main Target: Gerald Wallace (Wallace is more of a SF but he can play the PF in spots and would be a nice complement to Al Jefferson. The issue, of course, is that in such a weak free agent class, he could demand more money than the C's can afford)
The Main Target: Desmond Mason (Can't shoot but is a very strong defender; probably will cost more than the C's can afford on a SF)
The C's blew out the Blazers and made Greg Oden's debut one to forget. That being said, Kwame Brown's summer league debut was very impressive so you never can tell. That being said, here are the intial reactions from the first game from Vegas.
The Main Target: Kelenna Azubuike: Azuibuike is a former teammate of Rajon Rondo who came out too early but has continued to improve his game. A solid defender and very good three point shooter, he could be this year's Matt Barnes. With holes at the PG and frontcourt, the C's can't afford to spend a lot on a backup shooting guard and Azubuike should be the best bargain.
