The deal with the Tigers does have an NBA opt-out clause, so a return to the NBA this season isn't out of the question--however, it's quite unlikely.
Flynn hasn't gotten 'back on track' since he had hip surgery prior to the 2010-11 season. Following 2010-11 he was traded that summer to the Houston Rockets for Brad Miller. Later in the 2011-12 season, Flynn was traded from Houston to the Portland Trailblazers, where he finished last season. The Blazers drafted Lillard and signed veteran guard Ronnie Price this offseason, so Flynn wasn't exactly 'in the cards' for a return to Oregon.
Flynn was invited to training camp by the Detroit Pistons, but was cut before the season began, resulting in Flynn's deal with the Tigers.
I certainly hope Flynn can turn his career around and one day be an effective player in the NBA.
That's all for now, thanks for reading HOWL and GO WOLVES!
