12 Free agents Dallas Mavericks must pursue after Klay Thompson signing

11. Daniel Theis

The Dallas Mavericks' big man rotation is likely set. But in an NBA era that has seen premier centers take centerstage, having another rim protector wouldn't be too bad. And Daniel Theis looks like a great fit with the Mavs because of his defensive IQ and mobility.

At 32 years old, the German veteran isn't probably looking to play many minutes, and his value to Dallas would be based more on his ability to play in spots, particularly when Dereck Lively II and Daniel Gafford are injured or dealing with foul trouble. That scenario took place last season when the rookie sustained a nasty injury during a matchup against the Portland Trail Blazers, and while Gafford was still suiting up for the Washington Wizards.

Theis' stats don't really show his defensive prowess, as his career averages are 4.8 rebounds, 0.5 steals, and 0.9 blocks per game. However, the eye test has displayed his capability of anchoring the defense.

Another reason the Mavs should pursue the journeyman is his improved outside shot. He has converted just 33.1 percent of his 3-pointers over his career, although last campaign saw him sink 37.1% of such shots. That's what Dallas sometimes needs from its big men to give Luka Doncic and Kyrie Irving space to operate with the ball.

The franchise might have some competition for Theis' services, though.

However, it could have an advantage if it decides to chase after the center in the form of Mavs legend Dirk Nowitzki, who has served as his inspiration.
