5 players the Dallas Mavericks should sign to fill their open roster spot

2. Patty Mills

If the Dallas Mavericks are set on adding a backup point guard but don't want to sign a young guard who isn't fully ready to contribute on a playoff team like Killian Hayes, they could consider signing a veteran who can play some spot minutes and run the second unit if needed.

None of the backup point guards would move the needle much for the Mavs if they signed them, but signing a veteran point guard who is a good leader and provides a positive locker room presence would be a good idea. If the Mavs go this route, they could consider signing Patty Mills as he was recently waived by the Atlanta Hawks.

This season, Mills is averaging 2.7 points, 1.1 rebounds, and 0.7 assists per game while shooting 37.3 percent from the field and 38.2 percent from downtown. He hasn't had the most productive season, but he has vast playoff experience and could be a spark plug off Dallas' bench.

Mills has played in 95 playoff games throughout his career and won the NBA Finals as a member of the San Antonio Spurs in 2014. He would join fellow Australians Josh Green and Dante Exum on the Mavs if they sign him, and would give the Mavs insurance at guard over the playoff push.
