In the midst of the dog days of July, there isn't much going on for anyone on the Dallas Mavericks besides training, rehab (for some players), and trying to relax ahead of another grueling 82-game season that could very well include the playoffs this year. A large determinant in Dallas making the playoffs next season will be if the performance of their guard corps suffices, as Kyrie Irving misses an indefinite amount of time next season rehabbing from a torn ACL, as newly-signed guard D'Angelo Russell will likely assume the starting role until Irving returns.
There were other options on the table for the Mavericks, though, such as Chris Paul or Malcolm Brogdon, but Dallas is hopeful they made the correct decision with Russell, being that he's in the middle of his prime and on a prove-it contract.
