I don't think Korver is shot. I think teams figured out that taking out the key role players on Atlanta is important to forcing them into bad shots. Just switch if you need to take away Korver threes or whatever you don't like and force them into 1v1 mismatches they can't really take advantage of.
And in the Teague situation, it only takes ONE bidder, ONE injury and someone may be interested. Before the deadline means you're getting 1 1/2 years of Teague, enough to make him like his new situation. He has a killer contract and won't hurt anybody's salary cap in the summer. If anything if he's an upgrade in his new situation he may improve the free agency chances of his new team as a prior all star.
East teams that could be interested are the previously mentioned Bucks obviously, even though I don't think they'll do a win now move.
The Knicks seem to be 1 quality player away of being a 7-8 seed. Maybe they'll go for it.
Memphis has recovered after a slow start and they may be 1 guard injury away from doing a silly trade.
Same goes for the Kings. I mean if we're talking stupid investments, they're the front runners.
The Suns may offer Markieff and an asset and the Hawks should at least think about it. If they have a happy Markieff until next year's trade deadline they probably can flip his contract for more.
What if the Rockets determine that Ty Lawson's return isn't going to happen in early February and they try to get an upgrade there? They got some interesting pieces they could attach to Ty.
Another wild card: WHat if the Heat say 'Goran Dragic is a good player but he doesn't fit our system and we don't want to alter the system to better suit his skillset'. Teague would be a good fit in Miami.
