Quentin Grimes Gives Lakers A Different Kind Of Marcus Smart Replacement

Quentin Grimes is not a clean Marcus Smart copy. That is the right starting point.

Smart left the Lakers for the Rockets on a two-year, $13 million deal, and Los Angeles moved quickly by adding Grimes on a reported four-year, $60 million contract. The question is whether Grimes can absorb enough of Smart's old point-of-attack work next to Luka Doncic and Austin Reaves.

A Lakers Reddit post made the statistical case through BBall Index perimeter-defense numbers. Grimes' average percentile ranks were listed at 83.6 percent in perimeter isolation defense, 79.0 in on-ball screen navigation, 88.8 in chaser defense and 82.6 in matchup difficulty. Those are strong indicators for a guard asked to fight over screens and take difficult perimeter assignments.

The 2022-23 season is the cleanest example. Grimes was used as a true point-of-attack defender that year, with matchup difficulty at the 100th percentile and perimeter isolation defense at the 98th percentile. The argument is not that he has always been placed in the perfect role. It is that his best defensive usage looks like what the Lakers need.

There are limits. Smart was stronger, louder and more versatile as a switch defender. He could guard up the lineup, create turnovers and set a defensive tone in ways that do not always show up in one metric table. Grimes is more of a balanced three-and-D guard.

That still matters for this roster. Doncic and Reaves will carry the offense, but neither should be asked to chase the toughest guard every night. If Grimes can take that job, hit open shots and keep the floor spaced, the Lakers get a practical replacement rather than a symbolic one.

So the framing should be narrow. Grimes is not Smart's emotional replacement. He can be the Lakers' best answer for the perimeter assignments Smart used to handle.
