HERE WE GO AGAIN: A WEEK OF FOOTBALL foofaraw leading up to the Super Bowl. Actually, since the contest for the best team in the NFL took place a week ago in San Francisco, this will be more of the Supernumerary Bowl. Nonetheless, when the 49ers and the Chargers tee it up in Miami on ABC on Sunday (Jan. 29, kickoff: 6 p.m. ET), the hoopla will be deafening: the interminable pre-game show culminating with Hank Williams Jr. bellowing “All My Rowdy Friends,” the ostentatious commercials, the half-time extravaganza with an Indiana Jones theme. Can you feel the electricity? Me neither.
