The NBA trade deadline is just around the corner. This is usually a time for teams to look to buy into or sell on their current roster.

This article goes into what we think the top nine contenders for the NBA championship need to do ahead of the deadline to improve their current roster.

Oklahoma City Thunder 

Needs - Perimeter shooting/extra depth.

Targets - Ayo Dosunmu, Naji Marshall, Aj Green, Malik Monk, Kevon Looney.

When you're the defending champions and have started this season as the best team in the league, there is not much they should change among their roster, but there are still problems that can arise.

They currently rank 14th in the NBA in three point percentage, so adding a shooter like Monk, Green, or Dosunmu would be a perfect addition to create spacing in the playoffs.

They have also been very banged up with injuries throughout the season so far, so adding just some extra depth would be very helpful. If they can find a way to snag Dosunmu without giving much up, I believe that would be the perfect scenario.
