I'm not instantly going to assume that Tinsley is striving for an NBA comeback because there are no quotes by him that state his motives for wanting to play in the D-League, but he probably wouldn't mind another chance in the league.
Personally, I think that Tinsley is making a good decision. It seems that once a player like him goes overseas (think Stephon Marbury, Steve Francis, Rafer Alston, etc.), they don't come back. Antonio Daniels played with the Texas Legends of the D-League last season and ended up being signed by the 76ers late in the season. Of course, players like Salim Stoudamire, Antoine Walker, Sean Williams, and Rashad McCants haven't made it back, but it's worth a shot.
Good luck, Jamaal! I wish you the best.
