Valentine, 27, is 6-foot-4 and spent each of his first four seasons with the Bulls. He appeared in 62 games last season, averaging 6.5 points and 3.2 rebounds.
Per Shams Charania of The Athletic, Valentine’s deal with Cleveland is for two years and partially guaranteed.
“Despite lukewarm career averages from Valentine (7.4 points, 3.5 rebounds and 2.0 assists), Cavs fans have some hope to draw from the sharpshooting guard,” wrote our Alejandro Avila. “Valentine’s ability to stretch out the court as a viable wing shooter adds plenty of stock off the bench.”
