The NBA, like any other professional sport, lives by one simple rule, 'What have you done for me lately?' Players can have enjoyed storied careers, given their best to perform day in and day out for their teams and the fans, but once they are no longer at that level, people stop caring. What's happened to Russell Westbrook and James Harden in the past year is an example of how past achievements just don't matter, but Kemba Walker is dealing with some much more real consequences. 

Walker is a multiple-time All-Star, one of the most skilled point guards in recent NBA history. His prime was spent on the Charlotte Hornets, with whom he could never quite achieve much team success. Subsequent moves to the Celtics and the Knicks showed promise but Kemba had the injury bug by then, and his game was severely hampered by that. The most recent trade saw him dealt to the Detroit Pistons, with whom he can't seem to agree to a buyout. 

Kemba Walker Says Nobody Has Reached Out To Him, But He Wants To Play Basketball Again

Walker is in a weird place, where he doesn't fit in with the rebuilding Pistons at all, but he still can't agree to terms for a buyout. In this, he finds himself on the sidelines, with no other team trying to make a move for him either.
