Very few things are absolutely certain in today's world, especially in the NFL. It is almost impossible to know for sure who will be where in 2012. Sure free agency has answered many of those questions through its first week.
But there are still many high-end players who remain team-less. And there are many on rosters now who will not be come opening weekend in September. That doesn't begin to speak of college players to be acquired in the draft or through free agency immediately after.
In other words, once all the chips are settled and the puzzle pieces put together, each and every team figures to look vastly different from the one that completed the 2011 calendar year.
For the Saints, and every other team, that means more young players are going to step up and take over key spots. They will either be taking the spots of veterans or replacing veterans who were not retained.
The disparity in the final rosters may be even more diverse for a Saints team that could learn of excessive penalties Monday stemming from the "Bounty Fund" reported a few weeks ago. Who are those players who will be replaced or see their roles diminish in 2012? Read on to find out.
