Not sure if this has been brought up before or not, but thought I would share. I don't have the NFL network but usually watch the "official review" online each week, which is a plethora of good info. I just did a quick search and found a 4 part series on Mike Carey giving a nice look at his life, career, and very indepth look at his work during the superbowl, I'll post the link, then just use the find button on the bottom right, then search "Who is Mike Carey"
