There are sure things and then there's what the Baltimore Ravens appear to be headed for going into their regular-season finale Saturday against the visiting Cleveland Browns. Coming off a 31-2 win at Houston on Christmas Day that gave the Ravens a one-game lead on Pittsburgh in the AFC North, Baltimore (11-5) enters this one as a whopping 17 1/2-point favorite. And it's understandable if one thinks the line isn't steep enough. After all, not only are the Ravens playing like a Super Bowl contender, but Cleveland (3-13) is playing like a team hellbent on earning the No. 1 overall draft pick.
