On Saturday, The Basketball Tournament kicked off and Jared Sullinger was on the sideline for Carmen’s Crew. He was the coach of the team filled mostly with Ohio State alumni. It’s a role he relishes. Yet it’s not a role he wants to assume permanently. Sullinger, the Celtics’ first-round pick in 2012 who enjoyed four solid seasons with the club, still has aspirations of returning to the NBA. He’s only 28 but hasn’t played in the league in three years. His post-Celtic career lasted just 11 games with the Raptors, and then Sullinger learned about the harsh reality of being injured and considered damaged goods.
