Obviously they won't fire him right before the post-season, but I think everyone can agree at this point that the miracle championship season was a fluke. It was Lebron, not Lue, that was essential to that run. 

One is a SHIT coach if one consistently loses to teams like the Bulls with the amount of talent that the Cavs have at their disposal. It's not a slump anymore, and it hasn't been one for a while. This is a lost team that plays with no passion or trust in their coach or teammates. It's really sad that a team with THIS much talent is dominating inferior opponents consistently.
