Bill Cowher dropped by Steelers practice on Thursday for the first time since leaving as the team's coach four years ago. Cowher did so for his job as a CBS analyst. He watched part of the practice with Mike Tomlin, who succeeded him as coach in 2007 and won the Super Bowl a season later. Numerous Steelers players hugged and exchanged handshakes with Cowher, who now lives in Raleigh, N.C.
