Cavaliers organization losing faith in David Blatt

There is a growing level of worry within the Cleveland Cavaliers organization about first-year coach David Blatt and his ability to reach the team, according to league sources.

Sources told that there is rising concern in team circles about the level of response that Blatt is getting on the floor, with Blatt himself acknowledging that the Cavaliers "lost our energy and we lost our competitiveness" in Sunday night's embarrassing home loss to Detroit.

The Cavs would prefer not to be forced into evaluating their new coach just 30 games into Blatt's NBA career, but the Cavs' effort level, especially defensively, is eroding noticeably, raising the volume of questions about just how much the locker room is listening to the 55-year-old Boston native, who has enjoyed tremendous international success but began this season as a relative unknown to NBA players.
