Aaron Williams is a big CB from Texas, much like our own Quentin Jammer. He's athletic and fast enough to play CB, but could project as a S. He rates somewhere between being the 3rd best CB in the draft and maybe the 6th best.
The Chargers could be interested since there is almost no depth behind Jammer and Cason and A.J. Smith has been known to look towards the future when it comes to CBs. I can't imagine the Chargers using their 1st rounder on him, but I could imagine him slipping to us in the 2nd round and being the best player available. He's not a favorite to be a future Charger, but he's somewhere on the radar.
