What we're watching: Monday Night Football begins its regular season in its normal Monday night spot (it actually started the regular football season last Thursday), airing a match between the Philadelphia Eagles at the Atlanta Falcons. It begins at 9 p.m. on ABC. It's in high definition, of course, as is Monday Night Countdown, a 90-minute preview show that airs at 7:30 p.m. on ESPN-HD.
