The Colts like to pride themselves on not changing things just for the sake of change. In the case of naming team captains, that philosophy very much makes sense.
Phil Wilson of the Indianapolis Star Tweeted a little while ago that the player captains for the 2010 Colts are the same as they were for the 2009 Colts.
It almost goes without saying that Manning and Brackett are the unquestioned leaders of this team. When you look at both men, they represent the wide net the Colts use to bring in quality players. Manning, a first overall draft pick in 1998 and the son of a great NFL quarterback in his own right, and Brackett, an undrafted college walk-on from Rutgers who many thought was too short to excel at the NFL level.
The always popular Adam Vinatieri has always been a special teams leader, and once again Melvin Bullitt is awarded a captaincy honor by his teammates. Bullitt might be one of the most under-rated players in the NFL. However, it's clear his teammates do not under-rate him.
