Brown was born in Laureldale, Pennsylvania, and graduated from Montgomery Blair High School in Silver Spring, Maryland, a suburb of Washington, D.C.

In the 1966 NFL title game at the Cotton Bowl in Dallas, Brown intercepted a fourth-down pass in the end zone by quarterback Don Meredith in the final minute, preserving the Packers' 34–27 victory over the Cowboys.

Brown finished his NFL career with 13 interceptions and six fumble recoveries, including one for a touchdown, and also returned 27 punts and 7 kickoffs.
