Save for his final season as a Green Bay Packer, Ernie McMillan enjoyed a long career as a starting Offensive Tackle for the St. Louis Cardinals, a team he played 14 straight years (1961-74).

McMillan started three Games as a rookie in 1961, and over the next 12 years, he was St. Louis's starter at Right Tackle over the next twelve years.  The former Fighting Illini went to four Pro Bowls (1965, 1697, 1969 & 1970) and was twice a Second Team All-Pro.
