5 Biggest needs for the Dallas Mavericks ahead of the trade deadline

4. A new backup center

Although it doesn't seem like it is the Dallas Mavericks' main focus, the team definitely needs to upgrade at the backup center spot.

The Mavs struggle tremendously when Dereck Lively II is out of the lineup or on the bench, and they must add a player who can protect the rim when Lively II is on the bench or out. Dwight Powell and Richaun Holmes are not the answer, but there could be hope in the trade market.

The Mavs have been linked to Daniel Gafford and Isaiah Stewart, and either player would be a massive upgrade over Powell or Holmes. This season for the Pistons, Stewart is averaging 11.0 points, 6.8 rebounds, 1.7 assists, and 0.8 blocks per game while shooting 47.0 percent from the field and 37.4 percent from 3-point range.

His improvement as a shooter is intriguing, and his energy and physicality could be contagious, but he doesn't have the size that Dallas needs at the center spot. Although he plays bigger than 6-foot-8, having a rim protector with size could be a better move.

Gafford is 6-foot-10, protects the rim, and has great touch in the paint. He is also an excellent offensive rebounder and plays hard. If the Mavs could find a way to land him, they could skyrocket up the standings in the West.
