That Ravens team had a hell of a run last year, and they got their title in right before the window slammed shut for awhile. I mean they may very well make the playoffs this year - but I doubt they win the AFC again. Though that conference is a complete crap shoot so.. who knows
All that said, had Rahim Moore played a pass correctly, they're not in the Super Bowl.. and the Patriots/Broncos are playing the 49ers. That's how small their margin of error was a year ago.
Then coming into this year, Newsome was stuck having to pay Flacco big money given his red hot January.. and the Ravens had a lot of turnover on the defensive side of the football.
So how we specifically differ, well, our cap "problems" wont come to light until the 2014-15 offseason.. our defense will not have substantial turnover like the Ravens did (may lose Bennett and Browner, but the rest should be back) and on offense.. figure that the key players will all be back and 100% healthy.
