PJ Williams & Kwon Alexander

This is the way the Saints do it with free agents. They place a value, offer a contract, and then they wait. Some players get better offers and leave (TA, Williams, Ingram) and some come back. Once in a while they pull an offer after replacing a player who doesn't sign, such as Ingram.

PJ, Kwon and TQS are likely all coming back at the number the Saints set for them.
Hopefully its after the draft. If you make it until then your getting the vet min or your remaining unsigned. Other teams would have filled out there rosters by then.
