Rice played college basketball for the Georgia Tech Yellow Jackets, but was dismissed from the team during his junior season.

He joined a highly recruited class at Georgia Tech, but was dismissed from school during his junior year following an alleged shooting.

As a junior, Rice was the 2008 Cobb County high school basketball boy's player of the year, according to the Marietta Daily Journal, as well as a third team (honorable mention) All-State selection by The Atlanta Journal-Constitution.

[13] Sources: Rice began his freshman season on the bench,[14] but he became a starter and played in all but one game for the 2009–10 Georgia Tech Yellow Jackets men's basketball team.

He scored in double figures six times, including the 2010 NCAA Men's Division I Basketball Tournament second-round game against Ohio State.

[20] As a sophomore, Rice posted six 20-point games,[21] but three times (all Georgia Tech victories) he played at least 10 minutes while scoring no points.

[23] In his return to the starting lineup on December 3 against the Tulane Green Wave, Rice not only posted his first double-double of the season with 11 points and 11 rebounds, but also had his first career 4-blocked shot effort.

[68][69] Rice made his professional debut in the Wizards' seventh game of the season on November 12, 2013, against the Dallas Mavericks, making his only shot (a three-pointer) and adding a rebound.

[70][71] After Rice's debuted by playing the final 79 seconds of a loss that caused the Wizards to fall to 2–5, head coach Randy Wittman said he would probably shuffle the lineup.

[71] In the following game against San Antonio on November 13, Rice played 13 minutes and tallied 3 rebounds while registering his first NBA steal.

[93] On August 15, 2017, Rice signed with TNT KaTropa of the Philippine Basketball Association as the team's import for the 2017 PBA Governors' Cup.

[94] His stint ended in disarray, as he was thrown out of TNT's do-or-die game against Barangay Ginebra in the semifinals after shoving Kevin Ferrer to the court then throwing the ball at him.

[100] Three days later, Rice recorded 27 points, along with 12 rebounds and 7 assists, including a buzzer-beating shot after a missed free-throw to send the game into overtime, in a 102–97 win over Maccabi Rishon LeZion.

[101] During his season with Holon, Rice led the league in scoring with 24.5 points and also averaged 7.9 rebounds, 4.7 assists and 1.9 steals per game.

He was named two-time Israeli League Player of the Month (for games played in November and February)[102][103] and four-time MVP of the Round.

[104][105][106][107] On April 9, 2018, Rice was released by Holon due to disciplinary reasons, after punching his teammate Guy Pnini in the face in the locker room.

[108][109] On June 8, 2018, Rice officially returned to Hapoel Holon for the 2018 Israeli League Final Four,[110] where they eventually lost to Maccabi Tel Aviv.

[118] Rice was subsequently suspended indefinitely by the Breakers,[119] but was cleared to return to the roster on December 6 after sitting out three games following an investigation by Basketball Australia.

[120][121] He appeared in one game upon being reinstated, but on December 9, his contract was terminated after he was arrested for breaching his bail conditions the previous night.

Rice made his debut in a friendly game against Lithuanian champions BC Žalgiris, scoring 10 points and dishing out 4 assists in a 102–71 loss.
