I don't see why it would matter if Lebron was consulted or not.
The problems with the team are pretty clear. Ray Allen and Chris Bosh were both marginalized greatly on teams with HOF teammates, but no one though that either wasn't a major contributor to the team. Sure, Doc sometimes says that he failed to fully integrate Ray Allen, but the general perception was that Allen was well fit to the role he ended up playing, whether or not he was being underutilized.
If everyone feels that Love isn't getting used well, either the coach is just no creative or the players are just incompatible. Now they can try a new coach before deciding if they need to trade Love.
