Colts coach Chuck Pagano gave a very emotional postgame speech following the Colts win over the Dolphins on Sunday, and it was one for the ages. During the speech he took off his ball cap and revealed a bald head due to recent chemotherapy treatments endured to fight his battle with leukemia.   According to Colts owner Jim Irsay, the players decided to honor their coach in the locker room on Tuesday by shaving their heads.  There is no confirmed word on the number of heads that were shaved, but long snapper Matt Overton, punter Pat McAfee, and kicker Adam Vinatieri were the first players to take the leap of solidarity.
