2012 best case scenario would be to steal D.Howard from the Magic. The Magic will still have money tied into Lewis, Nelson, Gortat, and other mediocre players that their Gm is bound to bring in. Without some real star support they will basically be headed for another empty championship run. Dwight will look at the magic then see the heat, Lakers, Celtics and whatever other superstar team that's bound to be formed by then and realize he needs to bolt. Then we pick up the pieces
.
Rondo will be the main selling point, Nelson can't get the ball to him they way Rondo can. We convince him we'll pick up another player, maybe Mayo maybe someone better. Then we convince him KG and Ray will resign for cheap if Dwight is coming. When KG, Ray, and Pierce contracts are all up we'll have the flexibility to either extend them or look for other pieces. The goofy **** can't say no to that can he? 
Howard alone would guarantee that we're a top rebounding and defensive team all we would have to do is find the offense (Rondo and some shooters
).
So it would...
Rondo a prime star
Ray 37, KG 35, Pierce 35 above average veteran role players
D.Howard a prime superstar
Just find a 3rd star or someone to take on the scoring role since Rondo's the playmaker and Howard's the defender, rebounder, and finisher.
If our cap after resigning Pierce, KG, Ray, extending Perkins, and likely Baby is around 44 millions or so, Dwight isn't on the table.
Even if we don't sign Baby OR Perkins after this season (a big, BIG risk), we'll still probably be at around 35 to 40 million or so.
I don't see how we'll be open to a max player.
Danny Ainge isn't going to re-sign anyone beyond 2012. The numbers you are throwing out for Davis and Perkins are outrageous. I believe this will be Danny's plan: Re-sign no one beyond 2012. Have only Pierce and Rondo on the books, with maybe Bradley and another rookie or two. Make a hard push to sign two near max free agents in 2012. Offer minimum contracts to KG and Ray. They will likely accept to play one or two more years with a reduced role while still being a championship contender.
2012-2013 lineup:
Rondo
Near max free agent
Pierce
Garnett
Howard
Sixth man: Ray Allen
Well if you're talking "outrageous", where do you get the idea that KG and Ray will take minimum contracts?
And as far as Perkins and Baby, 8 million per is FAR from that. Perkins was signed to his current extension of 4.3 million after coming off of a 4.5 point 6.2 reb season, where we won nothing.
He's been a key part of 1 championship team and 1 runner up, and plays maybe the best man post defense of anyone in the NBA. He averaged 10 points and 7 rebounds last season, and he'll be 26 next season. At age 29, Brendan Haywood averaged 9 and 9, and got a 6 year 52 million dollar contract.
Glen Davis is proving that he can increase his previous per minute production with higher minutes. That is an expensive commodity.
8 million dollars per could move either way, but its not outrageous. Now, if you think they won't resign either player in a lockout year, I believe it. But, someone will, at a rate comparable in the new CBA.
