They can't wait to next offseason, Garnett will be a FA next offseason.
2. To wait until the deadline is utterly stupid, Garnett makes 22M$ a trade at the trade deadline will hurt the Wolves A LOT more. Trading Garnett is hard enough, at the deadline it will be nearly impossible.
Edit: Trading Garnett at the deadline WILL be impossible. The team that trades for him has to bring up all those salaries, they can't extend his contract, they have to pay his kicker if he doesn't waive it and they face losing KG in the offseason again.
The Wolves have absolutely no leverage if KG privately asks them to trade him or that he is opting out next offseason.
Conferences also mean little in KG's case.. If they trade KG they are in total rebuilding mode and are YEARS away from competing with the top teams anyway. They will also have to respect KGs wishes and Garnett in most trade scenarios will have the last say wether he wants to go there or not as no team will accept his trade kicker and take him if he is not telling them that he will sign an extension with them.
The Lakers have leverage, they are not that bad of a team, Kobe is signed for more years, Kobe is younger, Kobe is cheaper. But the Wolves? They have no leverage at all, ZERO.
