L.A. Clippers guard Patrick Beverley is one of the best perimeter defenders in the NBA. Great defenders such as Beverley often get asked who their toughest cover is. George Efkarpides of EuroHoops asked the former All-Defensive First Team member who has been the toughest player to guard so far in 2019. His answer? Sweet Lou Williams in practice.

Beverley's praises came after Williams dropped 34 points on 14-of-20 shooting in just 23 minutes off the bench to lead Los Angeles to a 140-115 win over the Boston Celtics. The two-time Sixth Man of the Year awardee also accomplished a historic feat on Monday night and became the NBA's career leader in points off the bench.

Beverley and Williams must have some very heated battles when they compete against each other in closed doors. It'd be safe to bet that Beverley brings the intensity to Williams every time in practice. Nonetheless, their intense match-ups must bring the best out of Williams every night.

With his most recent feat, Williams is making another run for top Sixth Man honors. He has raised his level of play in every month this season, and more so in 2019, as Beverley alluded to.

At the turn of the calendar year, Williams has been averaging 22.8 points, 3.4 rebounds, and 5.9 assists per game, while shooting 43.7 percent from the field. His 2019 stats so far are identical to his numbers last season, where he won his second Sixth Man of the Year award.

The name Lou Williams is almost synonymous to Sixth Man at this point. Without a doubt, Sweet Lou is a vital piece of the Clippers' unexpected run at the playoffs this season.
