I believe Williams is 1B.
For Richt to go from wanting to start a QB that was perfectly versed in His system, to making that "need to know" comment today, is telling.
Bigger indictment of Perry, don't think He's ever averaged double digits on yards per completion since He's been here from the stats I've seen.
For somebody with a strong as arm as Him, He sure seems to throw a lot of check-downs.
