Four to five other teams are still expressing interest in signing point guard Austin Rivers, as the Memphis Grizzlies haven't made a formal offer to him yet, according to Shams Charania of The Athletic and Stadium.

The Washington Wizards traded Rivers to the Phoenix Suns, who are reportedly going to reach a buyout agreement with the 26-year-old. Charania reported earlier Tuesday that Rivers was expected to sign with the Grizzlies upon his buyout:

In 29 games with the Wizards this season, Austin Rivers averaged 7.2 points, 2.4 rebounds and 2.0 assists per game while shooting 39.2 percent from the field, 31.1 percent from beyond the arc and 54.3 percent from the free-throw line. He is best suited in a sixth-man role where he can come off the bench and score the basketball. For whatever reason, it just didn't work out in Washington.

According to Brandon Robinson of Heavy, the New Orleans Pelicans, Golden State Warriors, Houston Rockets and Dallas Mavericks reportedly have interest in Austin Rivers as well. Rivers began his NBA career with the Pelicans and was teammates with Rockets All-Star guard Chris Paul with the LA Clippers.

Rivers is something of a lightning rod in NBA circles since he is the son of Clippers head coach Doc Rivers, but he's a good player who can score in bunches and create for others. It will be interesting to see where the former Duke Blue Devil ends up.
