The one biggest issue that hasn't been decided yet but should be today, that will steer the rest of the Saints decisions is the 2014 Salary Cap.

Negotiations are ongoing presently and the actual salary cap could be anywhere between 129-135m. I know the negotiation term is somewhat confusing as the Salary Cap number is believed to be based on revenue numbers but there is a little more to it than that.

Example: (as close as I can speculate)
There are actually TWO cap numbers. There is the Compensation Cap which is based on revenue, and there is the Salary Cap which is based off of negotiation.

E.g. The 2014 Compensation cap based off of revenue calculation may be $150M, but the NFLPA has to negotiate what percentage of that goes to Salary, and what percentage of that will go to Benefits (medical, retirement, etc...) So basically you start with $150m, determine 11% will go to Benefits and 89% will go to Salary eg 132m salary cap.
