It won't be an easy task, but the Browns will start rookie quarterback Colt McCoy for the first time against the Steelers on Sunday. "It's go time," Browns offensive coordinator Brian Daboll said. "He's facing the No. 1 defense in the league. What better way than to start out against the Pittsburgh Steelers? This is what he's always dreamed of." McCoy has been thrust into the starting lineup following injuries to Jake Delhomme and Seneca Wallace, who are both nursing high ankle sprains and could be sidelined for several weeks.
