Former Pittsburgh Steelers coach Bill Cowher is returning to the NFL ? as an analyst on CBS' Sunday "The NFL Today" studio show. Cowher resigned as the Steelers' coach last month following 15 seasons, and less than a year after winning the Super Bowl. He said he wants to spend more time with his family in Raleigh, N.C., but that working on the CBS show will allow him to keep his ties to the league. Cowher, speaking on a conference call Thursday, did not rule out a return to coaching but said, "I'm planning on doing this for a couple of years. CBS will add Cowher to the show without any of the other analysts leaving ? Dan Marino, Shannon Sharpe and Boomer Esiason will return, as will host James Brown and former NFL general manager Charlie Casserly.
