Buffalo to pass on Clausen?

We're beginning to hear rumors, from multiple sources, that the Bills could pass on Jimmy Clausen with their first round pick and take Dan Williams, the DT from Tennessee, instead. This could cause Clausen to drop all the way to San Francisco's 2nd pick at 17. If he doesn't get picked there, he could potentially fall out of the first round, completely.

If Buffalo does pass on him, look for them to try and take Tim Tebow with their second round pick.
