Undrafted rookie Matthew Dellavedova has signed a two-year contract with the Cavaliers for about $1.3 million but only a small portion of this season’s deal is guaranteed a league source confirmed Thursday. The signing was first reported by Australian media.

Dellavedova averaged 2.8 points and 3 assists in five summer league games with the Cavaliers after leaving St. Mary’s as the school’s all-time leader in scoring assists games played free-throw percentage and 3-pointers. He played for the Australian Olympic team last summer but the biggest knock against him is a lack of athleticism.

Dellavedova has an excellent chance to make the Cavs as a third point guard.
