The Mavericks open training camp on Sept. 27 and it's time to break down players who appear likely to make the final roster:

Salah Mejri

Age: 30

Size: 7-1, 245 pounds.

Key stat from 2015-16: In 34 games as a rookie, he averaged 3.3 blocks per 36 minutes played. That was second in the league last season.

Contract status: Signed through 2018, scheduled to make $875,000 this season.

2015-16 in review

A completely unknown quantity coming into last season, Mejri showed he has at least one NBA skill with his ability to block shots. He rejected Oklahoma City's Kevin Durant and Russell Westbrook in the same game. Other than that, he's not a polished defender, but he can score and rebound if you don't pay attention to him, as evidenced by back-to-back double-doubles against Portland when he averaged 13.5 points and 13 rebounds late in the season.

A very agile big man, he should give the Mavericks a nice change-of-pace center behind Andrew Bogut. And with Mejri, Bogut and rookie A.J. Hammons, the Mavericks should be able to keep a shot-blocker on the court at all times, if they so choose. Mejri's biggest challenge will be proving he can handle the NBA grind. He needed to get stronger over the summer and spent plenty of time in the weight room. Now the Mavericks need to find out if he can be the backup center or if they'll have to lean more on Hammons or third-year player Dwight Powell, who is more suited for power forward.
