3. Backup point guard

This need is nowhere near as pressing as the Dallas Mavericks' need for a starting center, but the Mavs do still need a backup point guard.

Dallas did attempt to address this need by signing Dante Exum to a two-year deal this offseason, and despite him having a great showing at the FIBA World Cup, he is still unproven.

It would have been ideal if Dallas could land a veteran facilitator who can handle playmaking responsibilities while Luka Doncic and Kyrie Irving are on the bench, but it does seem like the Mavs are going to be leaning on Exum.

If Dallas doesn't lean on Exum, most of their other guards off the bench are just microwave scorers. Players like Seth Curry, Tim Hardaway Jr., and Jaden Hardy are all players that are great scorers from the guard spot, but none of them are known for their playmaking or defense.

This may not end up being as big of a need as expected, as Irving spends a good chunk of time on the court when Doncic is on the bench, but Dallas truly didn't add anyone who can fully be trusted to lead the second unit.

Hopefully, Exum is a pleasant surprise this season and turns into a great backup point guard, but if he isn't it will be quite interesting to see who Dallas hands the ball-handling duties to.
