The Ravens have had four other chances to sweep the Steelers, but fell short. It's a task that is easier said than done, according to Ravens outside linebacker Terrell Suggs."It ain't just Pittsburgh," he said after the team's 17-10 victory over the Tampa Bay Buccaneers kept the Ravens tied with the Steelers at 8-3 and in first place in the AFC North. "It's very hard to sweep a team in the NFL. But it has been done, it can be done. Like I said, we'll be ready to play the game on Sunday night. No game is won on paper."
