Unless you are a diehard Packers fan or an NFL junkie, the name Forrest Gregg may not ring a bell. However, the Hall of Famer is arguably the best player to ever play his position. A 15-year pro, Gregg made a name for himself at right tackle. While manning the position for the Pack, Gregg was a six-time First-Team All-Pro. In 1965, Gregg shifted inside to play right guard due to injuries within the line and he was sensational — earning All-Pro honors yet again. From 1956-1970, Gregg won five NFL Championships and two Super Bowls with Green Bay.
