ST. LOUIS — Todd Gurley heard the fans chanting his name. The rookie is commanding that kind of attention. Gurley rushed for 128 yards and his first two NFL touchdowns, helping the St. Louis Rams put away the Cleveland Browns 24-6 on Sunday. “It’s not all me,” he said. “We’ve just got to keep improving and executing.” During the week, coach Jeff Fisher said Gurley wasn’t yet 100 percent.
