Clowney. It is really coming down to him, if they are going to address Edge at all before the year. They do have a history of waiting until they see the need and pulling a deal for Edge during the season (Fowler, Miller).
Best case for me the rest of free agency is to (not necessarily in order):
1) Extend AD, Coop and A'Shawn (moving money forward, when the cap is going to jump up with new TV deals)
2) Extend McVay and Snead
3) Sign 2 or 3 of Edge, ILB, CB, S. Names to consider are Clowney, Gilmore, Wagner, Honey Badger and others.
4) Prepare for the next Super Bowl by purchasing increased quantities of alcohol and ensure the parade stage has a photographer-proofed barrier/railing.
