I would be more surprised if Kobe doesn't play honestly.
If he says he wants to, then there's no way he isn't going to be on the team.
There's far too many ways to rationalize it, by saying that he's a leader, two time olympian, veteran leadership, can still play a bit when surrounded by stars, yadaydayda
Then you factor in the fact that it's Kobe, and it's a Nike team. The last time anyone will ever see him play basketall, ever. Off of this alone it's too much money to be made for him not to go if he wants to.
