Well, if they lose Watkins and Johnson, and don't sign any real big ticket guys, then they would likely get two 3rd round comp picks.
They can then utilize their cap space on adding few young mid priced players or stop gap vets, and lock up Donald & Joyner.
Then re-sign role players like Cody Davis, Matt Longacre, Havenstein, and Jamon Brown. Not to mention to set aside cap space for Gurley's new deal.
So this way you fill some key holes, while still developing guys like Reynolds, Everett, Goff, Higbee, John Johnson, Fox, etc... then you get the extra picks next year.
