Green had an up-and-down year with the Miami Heat last season, bringing athleticism and an improved focus on defense off the bench behind Dwyane Wade but was largely ineffective because of a prolonged shooting slump, particularly from long range, and uneven play.
With the rapid development of rookies Justise WInslow and Josh Richardson along with the rise of Tyler Johnson, there was less of a need for Green over the course of the season and his minutes, and his place in the rotation, fluctuated as a result. With the departure of Wade, the Heat are now fully committed to continuing to develop their young core and there didn't appear to be much interest in bringing him back.
Miami has since signed forwards James Johnson and Derrick Williams in free agency over the summer.
Green finished his lone season in Miami averaging 8.9 points on .392 shooting from the field and .323 3-point shooting in 69 regular-season games, starting 14 of them.
