The new CBA has provided a new way for teams to reduce their cap hits. Every team is allowed to designated two players for re-sign in a way that reduces their cap hit by up to $1.25 million combined. In order to qualify for this benefit, the player must have been with his current team for at least four years, and only his current team is allowed to offer that benefit. So basically, it's a way for veteran players at the lower end of the roster to earn some more cash that doesn't hurt his team's cap. Here's a link:
To be eligible for the VSB, a player must have continuous service with a team for four seasons (he cannot have been cut any time), be a free agent re-signing with the franchise, and can only sign a one-year deal.
The bad news is, on the Saints, I see only one free agent who could possibly qualify for the benefit this year: CB P.J. Williams. And I'd be more than surprised if he'd settle for such a small deal anyway, even with the benefit.
