The Cavaliers did not waste time after the free-agent negotiating period began Sunday.

According to a source, the Cavs contacted Toronto Raptors guard/forward Morris Peterson shortly after the market opened.

Peterson, according to the source, is interested in playing for the Cavs because they are a "championship-caliber" team. Playing time also is important to Peterson, said the source. Peterson wants to become a starter or get significant playing time. He lost his starting spot this past season.

The Utah Jazz, Golden State Warriors, New Orleans Hornets, Miami Heat and Sacramento Kings have all expressed interest in Peterson.
