The Giants and Rangers are fine right now. The Knicks need to basically let every bad contract expire and then start over in a few years. Had they been smart enough to do this 4 or 5 years ago we'd have a good team now, but the Dolans are amongst the most braindead owners in North American professional sports.
However, I'll go with the Mets since they're the only team I like that shouldn't suck but does. Minaya NEEEEEEEDS to finally address the bullpen in a big way, and by that I mean we need changes from top to bottom. With Wagner out all of next year they need a closer not named K-Rod, and they need at least one reliever who can get a righty AND a lefty out in the same fucking inning. They also may need to pick up a back end of the rotation starter if possible. The offense seems to choke down the stretch but if the pitching staff was a bit more competent between games 1 & 142 they would be able to slide into the postseason even with the inevitable 6-14 to 8-12 finish.
