Indianapolis Colts: 15 best free agent acquisitions of all-time

Unlike most of the players on this list, Jeff Saturday never played a game with another team. But he was signed by another team first, which technically makes him a free agent. He was undrafted and was signed by the Baltimore Ravens, but was ultimately cut before playing a game.

The Colts decided to take a chance on him, and boy, did it ever pay off. Saturday was selected to the Pro Bowl five times with the Colts, and was First-Team All-Pro twice as well. He was a constant along the offensive line during the Colts’ golden years.

Saturday was a strong center who was a heady player. He was perhaps the smartest player on the field besides Peyton Manning. He made all the right calls along the offensive line and was as tough as they come. He didn’t miss a start from 2000 to 2004 until an injury late in the 2004 season.

Saturday helped bridge the gap between franchise quarterbacks. While he never played with Andrew Luck, he was the center the year before he got drafted when they went through spells with Kerry Collins and Curtis Painter as their starter.

Saturday is undoubtedly the best center in franchise history. He has his name in the Ring of Honor, and some day should have a gold jacket as a member of the Pro Football Hall of Fame. While there might be some doubt to his candidacy, there is no doubt about the last guy on the list.
