There is obviously a run of storylines leading up to Super Bowl XLVII. The brothers Harbaugh, of course, have been -- and will be -- discussed at great length. It could be the last game for Ravens safety Ed Reed. It is the last game for Ray Lewis. But there is one piece of beautiful irony that has been overlooked, something so delightfully full circle. Lewis' first career sack, in 1996, was of San Francisco 49ers coach Jim Harbaugh. At the time Harbaugh was quarterback of the Indianapolis Colts and Lewis was playing in just his sixth career game.
