I keep reading this over and over again in these threads where some Saint's fans insist that is the rule and that apparently is not the rule, or at least is not how officials interpret the rule. This interpretation was not made up for this game. I have seen that call before in a game this year. If it was just a matter of the heel touching, that was very obvious and would have been to the replay official. http://profootballtalk.nbcsports.com/2011/12/12/in-the-nfl-a-toe-is-a-foot-but-a-heel-isnt/
