On Tuesday, the Los Angeles Lakers traded veteran guard Lou Williams to the Houston Rockets for veteran small-forward Corey Brewer and an unprotected first round pick.

Corey Brewer was a beloved teammate and well-trusted by Mike D’Antoni and the Rockets’ coaching staff. However, Brewer was unable to find consistency from the corner, or anywhere beyond the three-point line. His defense yielded positives and he did well with +/- numbers alongside Harden, Gordon, and Beverley. But his poor shooting brought about an additional burden for James Harden, with teams overloading and zoning to the strong-side, helping off of Corey Brewer — allowing teams to trap and blitz Harden off every pick-and-roll (taxing over the course of a long season).

With Lou Williams, the Rockets will have a reliable three-point shooter and a capable combo-guard who can adeptly run the pick-and-roll and create scoring opportunities for himself and others. Williams is shooting 39.6% on catch-and-shoot opportunities. In the first 9 seconds of the shot-clock, a time period the Rockets run a majority of their offense in transition, Williams is shooting 41% from three. The Lakers, as a team, scored 1.07 points per possession with Williams as the primary ball-handler in a pick-and-roll, ranking in the 94th percentile in the NBA (he’s run the 11th most pick-and-rolls in the NBA this season). That percentile is likely to go up when playing with a roster that is loaded with shooters who can score on spot-up and catch-and-shoot attempts.

With Lou Williams now a Houston Rocket, here are three areas to watch for.
