CLEVELAND (AP) The Cleveland Cavaliers have fired coach David Blatt and replaced him with top assistant Tyronn Lue.

General Manager David Griffin said Friday night that the Cavs had been taking steps back and were lacking connection.

Griffin says the team isn't in the business of being ''pretty good.''

Blatt led Cleveland to the NBA Finals last year. He was fired one day after expressing frustration with criticism of a team that's 30-11 and the top team in the Eastern Conference.

Lue is scheduled to make his debut Saturday night when the Cavs host the Chicago Bulls.

Griffin says Lue is not an interim coach and has the ''pulse of our team.''

Blatt was 83-40 with the Cavs.
