Defensive end Kevin Fagan and his mighty mustache helped hold the line for George Seifert's boxer's-mentality 3-4 defensive scheme during the zenith of San Francisco's 1980s power.

Fagan served stolidly in the d-line trenches alongside such fellows as Pierce Holt, Larry Roberts, the unforgivable Jim Burt, Danny Stubbs, Antonio Goss, and the immovable Michael Carter.

Fagan received NFL championship rings for wins in the oh-so-close Super Bowl XXIII against the Bengals, and as part of Super Bowl XXIV blowout of the Broncos -- at which time the 49ers' 1989 franchise staked their claim as the greatest football team of all time.

Being a lineman in a 3-4 scheme means forcible anonymity. But today, we remember and recognize Kevin (and his mustache) for the hard work put in.

Well done, Kevin.
