5. Mike Miles Jr.
The Dallas Mavericks' two biggest moves of draft night came in the first round as they drafted Dereck Lively II and Olivier-Maxence Prosper, but one move from after the draft could prove to be crucial as well.
Right after the draft's conclusion, the Mavs signed Mike Miles Jr. from TCU to a two-way contract. Miles Jr. is a homegrown product as he played at Lancaster High School and then TCU and fans should be excited about his future.
Miles Jr. had a good feeling he was going to Dallas, and it didn't take long for Dallas to call him after the draft ended. Although Miles Jr. may not play heavy minutes off the jump, a successful training camp could propel him into a reserve role.
Dallas' guard room off the bench is quite crowded as they have Seth Curry, Tim Hardaway Jr., Jaden Hardy, Dante Exum, and Miles Jr., but the only two true point guards in this bunch are Exum and Miles Jr. If Exum struggles and Miles Jr. thrives we could see him get some minutes early.
This seems unlikely at this point, as Exum looked like he would be a great fit during the FIBA World Cup, but Miles Jr. definitely does have something to prove at camp. He is a solid defender, a good shooter, and has a great handle.
Miles Jr. may not play on a nightly basis right away, but a productive training camp could work wonders for the young point guard.
