Cris Collinsworth has praised the San Francisco 49ers' rookie cornerback Renardo Green for significantly enhancing the team's defensive capabilities. Despite a challenging season, Green's presence in the defensive backfield has allowed the 49ers to compete effectively in man coverage, a notable improvement from previous performances.

Collinsworth highlighted Green's impact during the recent game against the Kansas City Chiefs, where he was instrumental in limiting star quarterback Patrick Mahomes' effectiveness. Additionally, rookie safety Malik Mustapha has also made a strong impression, stepping up in the absence of Talanoa Hufanga.
