Guido Merkens

Guido Albert Merkens, Jr. (born August 14, 1955 in San Antonio, Texas) is a former professional American football player who played quarterback, running back, wide receiver, punter and Defensive Back for ten seasons for the Houston Oilers, New Orleans Saints and Philadelphia Eagles of the NFL. In his first two seasons in the NFL, he was primarily a punt return specialist. During his tenure with the Saints, he served as the third-string quarterback, holder for field goals and special teams player; with occasional time as a wide receiver or safety.

In Houston during the 1970s, playing primarily on special teams, his penchant for being the emergency backup for all of the aforementioned positions earned him the popular aphorism "Jack of all trades."
