Guys a joke! You have a chance to play anywhere in the NBA you take it in a heartbeat.
Why? This kid has a ton of value, and no reason to rush it. Players and agent control the NBA, and they can get players to where they want. The kid is barely 20 years old, and he still has a lot of work to do before being much in the NBA. It doesn't hurt him to wait it out another year or two (and make good money in Europe) and put the pressure on Minnesota to get something for him.
Anyways, I am sure his list is more flexible than those 3 teams, those are probably just ones he had recently mentioned.
As for being a career backup...not sure where you are getting that. He will be looking to be a starter as soon as he can wherever he goes.
