Walker was forced to retire back in 2008 after an atrocious season with the Minnesota Timberwolves and has been trying to get back into the NBA ever since.
He filed for bankruptcy back in 2010, encountering money troubles fewer than two years after his retirement despite the fact that he made over $100 million in his 12 years in the NBA.
Determined to make his way back into the NBA and find his way into some more money, Walker was acquired by the Idaho Stampede, the NBA D-League affiliate of the Portland Trail Blazers.
He played there for two seasons before giving up the dream and retiring once and for all.
At this point it seems like Walker has accepted his fate and is ready to see what he can offer in a role behind the scenes.
Walker, who played seven seasons with the Boston Celtics (plus another half a season later in his career), has not spoken lately with Danny Ainge, the team's president of basketball operations.
His presence on the court as a big man who could also shoot from a distance is exactly what most NBA teams are looking for these days.
With his experience, picking out big men who could space the floor like he used to is something that could come naturally to Walker, or this could just be another one of his many failed post-NBA endeavors.
