5 Biggest overreactions to week 1 of the Mavericks' season

3. Grant Williams is the third star

Like Tim Hardaway Jr., Grant Williams is lighting it up from 3-point range. Williams is top-10 in 3-point percentage, shooting 55.2 percent from distance. And of all players in the top 10, he's made the most threes, making 16 shots from beyond the arc.

The former Celtic has been a difference-maker as a starter in Dallas. At his previous stint, in Boston, Williams never averaged double-digits and never looked like a super dangerous 3-point threat. He had his moments, but he was never labeled as a sharpshooter.

Now in Dallas, Williams has transformed into a volume 3-point shooter who can also defend the best opposing forward. While he's been known as a valuable defender, his offense has always lagged.

But if Wednesday's contest was a display of what's to come for Williams, the sky is the limit. He knocked down 7-9 3-pointers. Williams tied his career-high in 3-point makes. As good as Williams has been shooting it, it seems likely that he'll surpass his career-high this season.

Not to discredit Williams, but he's not the type of player to knock down 50 percent of his threes. Realistically, no such player exists. Dallas will be thrilled if he can shoot over 40 percent from three this season, and that seems like an achievable feat.

Once Williams cools down from beyond the arc, his appeal will fade. While he may not be the third star he's looked like to begin the season, it's obvious he'll be a fixture in the Dallas rotation.
