William Levi Johnson Sr. (September 14, 1926 – January 7, 2011), frequently known by the nickname "Tiger", was an American professional football player and coach.

Among his siblings was older brother Gilbert Johnson, who played quarterback at Southern Methodist University with the iconic running back Doak Walker.

He was a phenomenal catcher at the collegiate level, but always stated that he would have never made it in "the bigs" due to a lack of ability in throwing out base runners when they would attempt to steal.

[1] Sitting in a bar with teammates Norm Standlee and Nick Susoeff, the rookie Johnson became the butt of a joke for collecting checks while unable to play due to the cast on his hand.

Johnson was heralded as the star of the offensive line of the 49ers, who constantly beat teams due to their ability to control the ball and wear down opponents.

[1] "Frank and I were close friends, so he hired me as his offensive line coach," Johnson later recalled, adding that due to injury he was forced to return to active player status during that season.
