5. Jonathan Kuminga
Another Golden State Warriors player who could be on the move at the trade deadline is wing Jonathan Kuminga. He has reportedly been frustrated with his role, as it has dwindled some as of late, and the Dallas Mavericks could be a team that could be interested in him. They already have been linked to Andrew Wiggins, and it wouldn't be a big surprise if they show interest in Kuminga.
This season for the Warriors, Kuminga is averaging 13.6 points, 4.3 rebounds, 1.5 assists, and 0.6 steals per game while shooting 51.3 percent from the field and 30.7 percent from 3-point range. Kuminga's 3-point shooting numbers are down this season, but playing in Dallas next to Luka Doncic and Kyrie Irving could help these numbers rise. He also wouldn't be asked to do too much offensively, and his defensive potential would be utilized in Dallas.
Standing at 6-foot-8 and having a 7-foot wingspan and 38-inch vertical, Kuminga is someone who would be a great starting forward next to Dereck Lively II.
Dallas' defense in that starting lineup would be much improved just by adding Kuminga, and his defensive versatility would be maximized playing in Jason Kidd's system. I don't see the Warriors parting with Kuminga easily, but he could be someone who takes the Mavs to the next level.
