The St. Louis Rams will retire Marshall Faulk's No. 28 jersey at halftime of Thursday night's game against Pittsburgh. But Faulk said he might have given up the jersey much earlier if the outcome of Super Bowl XXXVI had been different. Faulk arrived in St. Louis in a trade from Indianapolis in 1999 and led the Rams to their only Super Bowl championship that season. Two years later, the Rams were heavy favorites against New England but lost 20-17 on a last-second field goal. Faulk decided to stick around hoping to get to one more Super Bowl. It never happened. "I think if we had won the Super Bowl in 2001, I would have retired that year," Faulk said Wednesday. "We didn't, and I felt like we still had it, so I came back. I was prepared to retire way before I did. All the time beyond then was bonus time for me." Sportscaster Bob Costas will preside over halftime ceremonies Thursday as the Rams (3-11) host the Steelers (9-5). A video tribute also is planned.
