You really think that Jordan would come off the bench on a team that missed the playoffs? He will lead them in scoring and play as much as he wants or simply, he wont be in uniform. What's in it for him?
Jordan is probably going to start the season as a 6th man if Jeffries shows he can handle being a starter or the Wizards sign a FA SF.
As the season goes on, depending on how the Wizards are doing, I think will dictate how Jordan plays. If he is resting a lot, playing off the bench and they are winning, he will keep it that way and take them to the playoffs if he can. If not, you may see him try to get more floor time to influence them.
What he gets out of it is probably his last go around in the NBA. He is also an owner of the team and his stake in this is not just immediate but long term. He is going to do what is best for the franchise.
