It's never easy to predict when a player is going to hang the laces up. There are guys still kicking around the league that probably should have retired a few years ago, and then there are retired players who could step on the court right now and still hack it.
From the team perspective, it's just as hard to identify when loyalty will win out over business savvy. Money is a good indicator, but some teams are more willing to reward past performance than others are.
Whether it's a lucrative contract, a successful career or a lengthy tenure with one team, all good things eventually must come to an end. The following players should be ready to start a new era with a different team, or close the book on their careers completely after this season.
