Easily the best defensive player in Colts history, Gino Marchetti might also have been the best pass rusher in the NFL for a decade.  Marchetti was also a great run defender and was regarded by many offensive players as the toughest player they ever faced.  The Pro Football Hall of Famer would be named a First Team All-Pro seven times and many have stated that the Colts would never have won the 1958 and 1959 NFL Championship without him.

The Colts retired his number 89.
