I'm sorry, but Mike Williams, why should we even think about him? He had 2 years under the person who is widely considered the best offensive line teacher in the league: Jim McNally, and only made slight improvement. He was outplayed by Jason Peters, a player that didn't really play OT until a year ago.
Williams is fat, and is a player that I've always thought was overrated just because of his sheer size. When you looked at Williams back when he was coming out and Leonard Davis when he was coming out, Davis was so much better than Williams. Williams was just big and powerful, that's all he had. No balance, no technique, and no consistency. And to this day, that's all he's ever been.
If anything, I'd move him to DT and try to make him a run stuffer.
Plummer would be an option. Two years ago, I would have said let's get Plummer instead of Webster. But now, I wouldn't be so quick to make the judgement. He's been nothing but a disappointment since the day Webster left San Fran. I might sign him if he's willing to accept nickel CB money.
