I know there are a ton of other reasons why we would go back in time that are more important than football, BUT how great would it be to go back to the Bills' War Room in 2006 and put the notion in Levy's and Modrack's ears,
"Mangold, not McCargo...;Mangold, not McCargo."
Hell, while we are at it, might as well power up the flux capacitor a little more to a couple of hours earlier and whisper,
"Ngata, not Whitner...Ngata, not Whitner."
