The Saints made a big splash year in free agency, signing guys like Darren Sproles, Aubrayo Franklin and Olin Kreutz (however brief his time in New Orleans was). They were showing people that they weren't going to sit back and be content. They struck quick in the free agency period, and struck often. It was amazing the quality of talent the were able to bring in with a limited amount in cap space.
This year will be no different. I map out the priority free agents (with the team or not) that will help this team be the first to be a true "home" team in a Super Bowl. When a coordinator is replaced, the person that takes his place will usually bring in guys who will match his scheme and who he is familiar with.
I also foresee the Saints taking on some cap casualties from disappointing teams who are overpaid for rebuilding teams, but who could come to New Orleans with a cheap price tag, a la Franklin.
So, you probably won't see the Saints go crazy this year in free agency, but who knows? Did anyone see that Sproles or Franklin signing coming?
