The rumor mill says Taj Gibson (pictured) is the source of many recent calls to the Chicago front office. But getting rid of Gibson would be foolish. It might be hard to see it through the frontcourt logjam of Pau Gasol, Joakim Noah and Nikola Mirotic, but Gibson is one of the best defenders in the game. If the Bulls want to win big this year, they'll hold onto their backup big man.

The Kings are perhaps the least predictable franchise in the league—and that's a bad thing. For ûber-talented center DeMarcus Cousins (pictured) to fully blossom, they need to give him some consistency and stability. And though their roster leaves plenty to be desired, new head coach George Karl needs some time to appraise what's there. Sacramento can only afford to move the ground under Boogie's feet so much.
Small forward Terrence Ross (pictured) is struggling, and recent buzz has general manager Masai Ujiri looking to swap him for Indiana Pacers veteran big man David West. That would be a mistake: West is a decaying player who doesn't fill a Raptors area of need when what they should be looking for is a wingman. Ross is a skilled 24-year-old who's likely simply undergoing a confidence crisis. Toronto shouldn't sell a dollar of the future for 60 cents in the present.
Golden State Warriors
The 42-9 Warriors are on Ray Allen's shortlist of teams he might join for a playoff run this season. But how can you improve on 42-9, and how can the best collection of marksmen in recent NBA memory need another shooter on board? It's tempting to bring in a shiny historical figure like Allen (pictured) -- or maybe even a different piece on the trade market -- but what Golden State has going is too precious to mess with.
The Pistons' record is far from terrific. But we mustn't forget their stellar January — a month when they went on a 9-3 run after jettisoning Josh Smith. That sharp, cohesive squad showed that, when they have a healthy Brandon Jennings, this is a roster worth watching. Moving big man Greg Monroe (pictured) or any other essential pieces would be a mistake: Detroit simply needs time and good luck in the draft and free agency.
