Houston Rockets free agency option #4: Garrison Mathews
Garrison Mathews entered the league in 2019 with very little hype or fanfare, as he was an undrafted free agent signing by the Washington Wizards. This shouldn't be surprising, as Mathews went to Lipscomb University of the ASUN Conference, where he didn't get nearly the exposure that he would have otherwise gotten in a power conference.
The Wizards added Mathews via a two-way contract and it didn't take long to prove his value at the NBA level. Although Mathews had difficulty finding playing time as a rookie (12.6 minutes per game), he averaged 15.5 points and 3.8 rebounds per 36 minutes.
What was even more impressive was his shooting efficiency, as he averaged a gaudy 69.1 percent true shooting, which led the Wizards entirely. Mathews made 41.3% of his long-range attempts in 2019-20, which was third-best on the Wizards, among players with at least 2 attempts per game.
After an impressive rookie season, Mathews gained much more playing time in 2020-21, as he played in 64 games, compared to just 18 games as a rookie. Mathews flashed his stellar outside shooting yet again, making 38.4% of his threes, which was again second-best on the Wizards, among players with at least 3 attempts.
Mathews' averaged 12.3 points per 36 minutes and had video game-esque shooting efficiency yet again, as he posted true shooting splits of 63.5%. The Wizards recently renounced Mathews' qualifying offer, making him an unrestricted free agent.
Through Mathews' first two years in the league, he's averaging 38.9% from three, making him easily one of the best shooters remaining on the free agent market. And at 24-years-old, he fits the Rockets' youth movement and their rebuilding timeline.
