Andre Barrett was as much a part of the fixture of the city’s summer streetball circuit as the muggy-hot nights out-of-control crossovers and late tip-offs. Only when June rolled around this past summer the former Seton Hall star was nowhere to be found. Rather than playing in multiple leagues on the blacktop Barrett was getting himself into tip-top shape looking to make one last run at the NBA at the age of 31. The 5-foot-10 point guard’s change of plans paid off on Wednesday when he signed a deal with the Grizzlies. As per team policy details of the contract were not released. “It definitely feels great” The Bronx product and Rice High School alum told The Post in a phone interview from Memphis. “I always felt it’s where I belong. It’s just a matter of getting the right opportunity. I proved I can play numerous times. It happens with everyone. You get that shot and you have to take full advantage.” The deal does not mean Barrett will be on the Grizzlies’ roster when opening night rolls around Oct. 30 in San Antonio against the Spurs. He is battling to be the team’s third-string point guard behind Mike Conley and Jerryd Bayless. He could end up back in the NBA Development League where he played last year or he could get cut. But Barrett is in an NBA training camp for the first time since 2008 when he was with the Clippers and has a shot to open eyes.
