FA: D'Angelo Russell Comes to Dallas | 2yrs/12mil

[Kidnova]

[Charania] D'Angelo Russell will have a player option in the second season of his two-year, $13M deal with the Mavericks, sources said.

I would have been surprised if this wasn't the case.  He sees this as a chance for him to score a bigger contract next season if he balls out until Kyrie comes back.
