Raymond Berry was all about the details with every aspect of his game.  An expert route runner, Berry rarely fumbled or dropped passes and was essential to the two consecutive Baltimore Colts Championships in the late 1950s.  Most notably, he caught 12 passes in the 1958 Championship Game for 178 Yards and a Touchdown.  

One of the best Wide Receivers in the history of professional football, Marvin Harrison spent his entire professional career with Indianapolis.  

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.

Had it not been for the greatness of Manning, Johnny Unitas would easily be at the top of this list and certainly would be for over half of the NFL teams in existence.
