The PJ Brown anouncement only further substantiates what Chris, BudweiserCeltic, Tim,and I have been saying...
Well-run teams with savvy front office chiefs, like Ainge, don't make single, isolated moves, like Nick stated previously.
Moves are made to fit within a plan, the further out the time line the more variables are left un-accounted for, so the moves with long-term implications are made with a "sliding scale" in terms of their low and high potential outcome.
While everyone has been arguing about Patrick O'Bryant and the rest of the youth, it is VERY, VERY probable that Ainge discussed Brown's future plans with him at the end-of-year wrap up and was informed that Brown would be willing to come back again if and when needed.
This helped Ainge to make his commitment to POB, because he knew that he could acquire a veteran backup later in the year by calling Brown for another title hunt. Instead of getting another mediocre vet early on, Ainge now has a chance to develop POB over the first 50 games of the season to see what he'd got.
Therefore, it is also EXTREMELY likely that Ainge has a "worst case" scenario gamed out in the event that none of the current wing players can fill the back up role.
The players available on the FA market this off-season were exceptionally mediocre outside of Maggette and Posey. We saw how much Ainge valued them by the offers he floated-minimum money for each and every one.
Considering the situation with Davis/Powe and considering the wealth of young talent currently on the roster,it is entirely likely that Ainge believes that it will be relatively easy to acquire a solid veteran wing later in the year, if and when needed.
He clearly shares the concerns of the more conservative members of this board in that he has shown his interest in having veteran insurance at the wing and in the frontcourt, but the VALUE he placed on the available options should show you how dire he feels that need is at the present time.
IF and WHEN necissary, Ainge will make a trade for a wing and bring PJ Brown back for another hurrah...getting a wing player, a veteran wing to play off the bench, is pretty much the easiest thing to do in basketball. Wing players are a dime a dozen position and getting the type of talent that this team would need from that position isn't very hard to do.
To name a few:
Dallas: Eddie Jones, Devean George, Jerry Stackhouse (not enough time for each, all cheap with short years)
Golden State: Steven Jackson (somewhat redundant with Maggette and team doesn't want to extend)
Clippers: Tim Thomas (expiring and they need a PF who could start for them)
Memphis: Hakim Warrick (another team needing PF depth, Warrick backs up 3 and 4, could be moved)
Milwaukee: Charlie V (unlikely to be re-signed and for good reason, but possible rental..future Tim Thomas in the making)
Minnesota: Brian Cardinal, Corey Brewer (long shots, but both could be on the block by mid-season. Cardinal is available for all takers, Brewer is fighting for his job with a number of wings who are both young and talented)
New Jersey: Trenton Hassell, Bobby Simmons (inner-division trade unlikely, but possible considering the different stages these guys are in.)
New Orleans: Rasual Butler (just became expendible with Posey coming in)
New York: Quentin Richardson (if he's healthy, he could contribute..2 year deal doesn't hurt the window Ainge is building)
Phoenix: Grant Hill (depending on what happens in Phx, could be available)
Seattle/OKC: Damian Wilkins
...and then their are all the un-signed vets who will be out of work due to financial restrictions and roster spots...and of course, we have our very own Brian Scalabrine who surely can fill the 12 minutes vacated by James Posey at the 3...he may not be much, but he can defend...
