There's absolutely no reason for the Bulls to trade Butler. None. Zero. He's their best building block by far, a good teammate, and is not asking for a trade. He is asking for other guys to be held to standards (i.e. Rose, Noah, Gasol most likely) because he cares about the team and about winning. He also was respectful enough to include himself in the players that need to be held accountable, and not mention names of other players. The Bulls are not trading Butler, if Celtics fans want a Bulls trade, then chose from Noah, Gasol, or Rose.
