Devin Hester, from one of my alma maters, used to do that (run back missed FGs) in the NFL. I was at a game in the old Orange Bowl between the Unversity of Miami and the University of Louisville (2 of my 3 alma maters), when Hester ran back 5 kicks. One was called back, so they redid the kickoff and he ran it back again, so only 4 actually counted.
