2 Ways Grant Williams can help the Dallas Mavericks, 2 ways he could hurt

Hurt 2. Skillset beyond a role player

Williams has averaged 6.2 points and 21.2 minutes per game in four seasons. He knocks in 45.1 percent of his shot attempts and shots over 77.3 percent from the free-throw line.

So, what's the problem?

Williams may not average anything more than that of what an average role player averages. In 79 games last season, he scored 20 points three times. In the playoffs, he never scored more than 14 points.

Defensively, Williams isn't a stat sheet stuffer. Williams has yet to average more than one steal and one block a game in four seasons. This isn't a big deal, yet NBA analysts base a player's career on statistics.

Regardless of his lack of defensive stats, Williams plays great defense. He proves his worth through physicality and energy Dallas needs this type of player in their frontcourt, but have fans overestimated Williams' potential impact?

Acquiring Williams solves the team's need for a three and D wing. However, he may not be the third star for the Mavs. Williams will be a great contributor for the Mavs, but likely won't be someone they can lean on offensively.

Unless Williams has a breakout season, it is safe to say that he could be nearing his peak.
