I will grant you that ND was lucky that the refs missed the two #2's. And Pitt missing the FG.
But those plays never would have occured if Wood had not fumbled as he was crossing the goal line in OT. That play was the opposite of good luck for ND.
Not to mention ND had the misfortune of guys missing time(Nix) and not being up to par due to the flu vs Pitt.
