NFL Defensive Backs have a reputation for being mean, hard-hitting guys. And many defensive backs like "Mean" Joe Greene, Dick Butkus and Ronnie Lott were just that.
Larry Wilson was the All-Pro Safety for the St. Louis Cardinals. He was an outstanding coverage player, led the league with 10 interceptions in 1966 and retired with a team record of 52 interceptions.
Joe Schmidt was one of the best middle linebackers in the NFL. He helped develop the middle linebacker position into the dominant pro defensive position. Schmidt entered the Hall of Fame in 1973.
