CBS'S The NFL Today, the patriarch of Sunday football pregame shows, returns this week with Jim Nantz as the modern-day Musburger, joined by Marcus Allen, Brent Jones and George Seifert. Two programming ideas to fill the show's expanded one-hour format: 1) Hire an in-studio band. Works for Letterman. Aren't the WNB-Ays between gigs? 2) Enlist NFL Today alumna Jayne Kennedy, now a psychic friend, to be the show's fearless forecaster. After all, she's more telegenic than ESPN picknik Hank Goldberg.
