Mays has shown during two different spells that he's capable of playing as an above-average emergency point guard. In 22 games as a Blazer, he's started 11 times and has averages of 9.6 points and 5.6 assists on 35.8 percent shooting from three.
He's on a partially guaranteed deal this season with Portland, but his spot minutes should be enough to keep him on the roster as end-of-bench depth, especially considering the injuries the team has dealt with to its backcourt this year.
Brown is to the center spot what Mays is to the guard position, except Mays has gotten more opportunities. The 7-foot-2 big man is a rim-deterrent and rebounder for nothing more than his size.
Brown has shown flashes of potential and is still only 24 years old, but he probably doesn't have a future in Portland. His $2.2 million partially-guaranteed contract could serve as salary filler in a trade.
