4. Spencer Dinwiddie
If the Suns are still in need of a point guard, pursuing Spencer Dinwiddie might be a decent move. It could also be easy to get him as he used to play with KD back in Brooklyn. Dinwiddie has proven himself to be a valued guard in the league and contenders can benefit from signing him.
He was bought out this season after he was traded by the Washington Wizards. Signing him could solve a massive problem that the Suns have faced all season long. With Dinwiddie controlling the ball, there's a chance that the team could execute their system better. Although he's not the best shooter from deep, the 6-foot-6 guard is capable of creating his shots.
