They finally have balance on both sides of the ball, but as the fifth-oldest team in the NFL, is the Ravens’ window of opportunity to win a Super Bowl closing? It’s an interesting question posed by Jamison Hensley of The Baltimore Sun, who explained that the long-time foundation of the team – Ray Lewis, Derrick Mason, Todd Heap and Ed Reed – is aging. But a similar question was raised in May 2006 when Hensley reported that President Dick Cass put an actual time stamp on the championship window. That year, Cass told fans at Spring Football Festival that the window was two years. http://blogs.baltimoreravens.com/2010/08/09/late-for-work-89-ravens-super-bowl-window-closing/
