The Chicago Bulls just finished another disappointing playoff run that saw injuries prevent the team from playing at full strength in the postseason. It seems to happen to Chicago every year, and they are one of the biggest "what if" teams from the last decade. Now, the team is probably saying goodbye to the head coach, but there may be more moves after that.

The team still appears to have the foundation for a contender, as Derrick Rose showed flashes of stardom during the playoffs, and Jimmy Butler has blossomed into a legitimate franchise player. But acccording to CBS Chicago, there could be tension brewing between the two players:

"Sources describe a passive-aggressive reaction from Rose that was the culmination of tensions building in recent weeks with Butler's emergence as a primary scorer. Butler is very aware that he won his bet on himself and is poised to reap the reward of a maximum contract from the Bulls, whether or not it takes an offer sheet from another club in restricted free agency this summer. Butler's emergence was validated by the NBA's Most Improved Player Award, and he's now feeling every bit the star, with all that entails."

There have already been rumors that Butler is being courted by the Lakers and Knicks, and for better or worse, Chicago is already tied to Rose, having given him a massive extension a few years ago.

Butler certainly looks like the better player currently and going forward, but Rose's contract is virtually untradeable. If he and Butler cannot get along, it could force the team to move on from Butler via trade before they lose him for nothing in free agency.
