Ken Berger of CBS Sports is reporting that Cavaliers' general manager Chris Grant is on 'shaky ground.'

Chris Grant has had a polarizing tenure throughout his time as Cavaliers' general manager, replete with questionable draft choices and perpetual uncertainties about roster construction.

That tenure may be coming to an end sooner rather than later, according to Ken Berger of CBS Sports:

As bad as it is in New York, a far messier situation exists in Cleveland, where Chris Grant's tenure as GM is on shaky ground, league sources say. No. 1 pick Anthony Bennett, who has made exactly five baskets in 110 minutes, may well have been pushed on draft night by coach Mike Brown. But Cavs owner Dan Gilbert just hired Brown for a second tour of duty and committed $20 million to him. Brown's recent indictment of the entire roster -- "We didn't compete," he said after a demoralizing loss to the Wizards on Wednesday night -- was awfully telling. We know Kyrie Irving is talented, but now we'll find out if he can be a leader, too. Right now, there doesn't appear to be one of those on the roster that Grant has assembled.

This is far from a surprise, given the Cavaliers' 4-8 start and their increased expectations coming into the season. While owner Dan Gilbert has not come out and said that it's "playoffs or bust" this season, that did seem to be the consensus coming into the season given the free agent signings made this offseason. I don't take much actual news away from this, but this report does serve as a confirmation that Gilbert meant business as far as seeing progress this season.
