Yes, they do.
The veteran shooter, who was bought out by the Los Angeles Clippers on Monday, would fit well into what the Bulls have already built this season and would be a solid insurance policy as the team begins the stretch drive towards the playoffs.
Butler has to clear waivers before he would be able to sign with the Bulls. The earliest he can sign is Wednesday.
But whether it's Butler, or another player, the Bulls have to add another body to the roster in the next week. That's because the team is only carrying 12 players at the moment, after trading James Johnson to Toronto last week, and they have a two-week window before having to add another player. The NBA requires that teams carry at least 13 players.
Whether Butler is signed, don't expect the new Bull to crack the rotation immediately. The Bulls aren't expecting a major impact from their new acquisition, no matter who it is. The Bulls are insistent upon keeping the close chemistry the team has already built this season and are unwilling to bring in someone who may upset that.
If the Bulls truly wanted to make an impact with a player who would have altered Tom Thibodeau's rotation significantly, they would have made a move to acquire a player at the trade deadline. They chose to stand pat, preferring to keep young big men Taj Gibson and Omer Asik, the two players almost all inquiring teams asked about.
