The NFL player's career is a transient one, with the possibility of change always right around the corner. The average NFL player who makes a team's opening-day roster only plays for six seasons, with that number being considerably lower for those many players that never get beyond a team's practice squad.
With this number in mind, the Baltimore Ravens will field a very different roster in 2013. It's mostly a younger roster with many of the team's older players either getting Super Bowl-influenced pay days with other teams or choosing to retire.
There could still be more small changes with the Ravens' depth chart, but with the early wave of free agency and the draft over with, it's doubtful that there will be any more sweeping changes. There will still be several starting jobs that will be fought over in training camp, though, and some older players who are making more money will need to justify their contracts if they want to stay in Baltimore beyond 2013.
Here are several players that are facing some pressure during the offseason workouts.
These aren't necessarily players that are struggling to produce: Some are here because of external forces, like a promising second-year player being behind them on the depth chart. Others could be dealing with the harsh realities of an NFL career, like recurring injuries or declining numbers that don't justify their current contract situation.
