The 49ers had a strong pass defense last season under former coordinator Steve Wilks, allowing the fourth-lowest passer rating in the NFL.

Pro Football Network’s Tony Catalina suggests that adding more depth to their defense, especially at cornerback, could take the team to new heights.

Player Kool-Aid McKinstry from Alabama is seen as a potential fit for the 49ers, bringing productivity and athleticism to the secondary.

With impressive stats from his college career, McKinstry could further strengthen an already powerful defensive unit.
