The source expresses skepticism regarding JJ McCarthy's NFL potential, noting that players from the Michigan era under Jim Harbaugh have largely struggled in the NFL, suggesting their success was tied to sign-stealing rather than individual talent. Additionally, McCarthy ranks near the bottom of the league in regular dropback accuracy filters within the Fantasy Points data suite.
