It's still hard to believe Kevin Garnett got traded. The most loyal man in the basketball agreed to play for the Celtics, which basically opened the floodgates to a deal that's been in place since before the NBA Draft. Garnett vetoed a trade before the draft, which killed the deal and allowed the Celtics to trade its No. 5 pick to Seattle for Ray Allen.
Having Allen and Pierce both in Boston had to be enough to sway Garnett, who then accepted the though of playing for them. He was then dealt for Al Jefferson (aka the centerpiece of the deal), Gerald Green, Sebastian Telfair, Ryan Gomes and Theo Ratliff's expiring contract.
What does it mean for the C's? Having Garnett, Allen and Pierce puts them in contention for the Eastern crown immediately. Rajan Rondo is the perfect point guard for them. Although he's young, he's a defensive stopper, who is fine without scoring a point. They'll have one weak spot on the roster and have a thin bench inside, but Kendrick Perkins is still there and draft picks Glen Davis and Gabe Pruitt might also be able to help some. Also, don't count out the possibility of a veteren signing with them for the minimum just to try to win a championship. They better do it in the next 2-3 years though, because GM Danny Ainge mortgaged the future for this one.
As for the T-Wolves, they weren't contending with Garnett and won't immediately after dealing him. They do have a ton of young talent though and might be a very good team in a few years. Randy Foye, Corey Brewer, Rashad McCants, Jefferson, Green and Telfair could all be very good. Since Garnett was going to walk in another year (probably) and they would be left with nothing, this deal was probably about all they could do.
Expect Garnett's cards and memorabilia to be on the rise. He's no longer in a small market and the C's are going to be on television a lot and could be one of the better teams in the league. The T-Wolves will have a lot of young players, who are going to get the opportunity to play immediately so it will be good for them also.
