The Houston Rockets are armed with an arsenal of cap space this summer and are preparing to unload it.

Kelly Iko of The Athletic reported the Rockets are expected to be aggressive in free agency, with Brook Lopez, Dillon Brooks, Cam Johnson and Austin Reaves among the team's potential targets. Houston has also been heavily linked to a potential reunion with James Harden if he decides to leave the Philadelphia 76ers.

Lopez and Brooks are set to be unrestricted free agents and could bring defensive presence to a team that's sorely lacked it in recent seasons.

Lopez is 35 years old and limited athletically, but he was the anchor of the Milwaukee Bucks' defense during the regular season. He finished second behind Memphis Grizzlies forward Jaren Jackson Jr. in Defensive Player of the Year voting while putting up his best scoring season (15.7 PPG) since 2016-17.

Brooks, who trash-talked his way into becoming a distressed asset on the open market, might wind up being one of the best values in free agency. He's a streaky but talented scorer who is comfortable taking threes from anywhere—even if it's not at a high-efficiency clip—and made the All-Defensive second team this season.

If he hadn't developed a reputation as an agitator and then folded during the Grizzlies' first-round series against the Lakers, Brooks would probably be looking at a significant pay raise from the $11.7 million average annual value of his last contract. Now it's unclear what type of interest he'll receive.

Johnson and Reaves will be hitting restricted free agency, which means the Rockets would likely have to break the bank to pry them away from their respective teams. Johnson is a consistent floor-spacer on the perimeter and has thrived both in a starting role and coming off the bench during his career. A career 39.3 percent shooter from three-point range, the North Carolina product can pretty much be slotted in any lineup and excel with whatever combination of players is on the floor.

Reaves was one of the most pleasant surprises of this NBA season, emerging as the third in command behind LeBron James and Anthony Davis during the Lakers' postseason run. While the Lakers were sent packing in four games by the Denver Nuggets in the Western Conference Finals, Reaves never shied away from the spotlight, putting up 21.3 points and 5.3 assists while shooting 56 percent from deep.

The Lakers will be motivated to keep Reaves, but they're limited to a four-year, $51 million contract because they only possess his early Bird rights. Los Angeles may wind up needing to wait out Reaves exploring the market and then match a contract above that mark.
