Contract negotiations are underway, and I think most of the players have contracts expiring this year and next year. I'm not sure if part of the collective bargaining includes scratching all the current contracts, which would effectively make all players free agents after this season.
The only reason I mention it this way is because I could see a bunch of the "stars" lining up and saying "Hey, I'd like you and you and you to come suit up and play with me at _____". Meaning players like Clark, Collier, Wilson, Stewart, etc. could effectively try to form super teams, or at least hand picked teams, depending on what the new salary cap looks like.
Could you imagine a team with Bueckers, Clark, Collier, Stewart, and Wilson? Doubtful they'd have the salary cap but it will make for interesting discussions...
