2. Bruce Brown
Durant had Bruce Brown as his teammate with the Nets. Their time together was fruitful, but they weren't able to contend for a title. Brown's stint with Brooklyn gave him a chance to grow as one of the best three-and-D players in the league. Phoenix could sign him as a potential replacement for Grayson Allen, who will likely leave in the summer.
Brown is a fearless defender who can also control the pace on the offensive end. He's currently with the Toronto Raptors and has played the point guard position in certain situations. Additionally, the championship experience he got from the Denver Nuggets will be useful.
The two-way guard has a team option in the second year of his deal, but there's hope that the Raptors will let him go.
