Ladies and gentlemen, your 2008-09 (On-Field) Asshole of the Year: Baltimore defensive back Daren Stone!
Stone commits a stupid personal foul that puts Baltimore, needing a field goal with 6:50 to go, at its own 14 instead of its own 39 yard line. The Ravens made it this far by not putting themselves in situations where Joe Flacco had to put the team on its shoulders. Stone pinned them back to a spot where Flacco had to throw. Two plays later, pick-six Polamalu and game over.
Speaking of which, the AFC had just one playoff team that would be a boring story in the Super Bowl: The Pittsburgh Steelers. How blase. Go Cards!
