Ray Lewis isn't exactly optimistic about his former team repeating as Super Bowl champions. The Baltimore Ravens underwent major changes with the loss of Lewis, Matt Birk, Anquan Boldin, Ed Reed, Paul Kruger, Dannell Ellerbe and Cary Williams among others. "It's going to be very hard, after you lose that much chemistry," Lewis told USA Today's Robert Klemko. "But who knows? It's unpredictable, as always. Hopefully, they try to pull enough together, use their youth and try to make a run. But it's hard to try that formula. That formula usually doesn't work." The Ravens did restock with Elvis Dumervil, Chris Canty, Michael Huff, Marcus Spears and Rolando McClain. General manager Ozzie Newsome said he didn't want to make the same mistake as he did after the first Super Bowl win and hang onto aging players too long. So he made moves with an eye on the future and to free up money for Joe Flacco and Torrey Smith and Dennis Pitta down the road. Source: NFL.com
