18. Miami Heat acquire Nick Smith Jr.
Although Miami's clear need is adding a new frontcourt player, drafting one at this position may be too big of a reach. They need a backup point guard, and Nick Smith Jr. is too good to pass up on at pick 18.
Smith Jr. was the number one ranked player in high school but had an injury-plagued freshman season at Arkansas. He still averaged 12.5 points, 1.6 rebounds, and 1.7 assists per game and battled back from his knee injury.
The Heat don't have a backup point guard, and he'd have the chance to learn behind Kyle Lowry. He immediately gives them much-needed guard depth, as they don't know if Max Strus or Gabe Vincent will return this summer.
Smith Jr. is an excellent ball handler and showed flashes of great playmaking. His assist numbers weren't great, but his handle allows him to get anywhere he wants on the court, and is good in the pick and roll.
He hustles on defense and his effort is never a question. Smith Jr. would fit great in Miami as their guards are great at backdoor cuts. That is something that Smith Jr. is good at as well as he can play on and off the ball.
