‘Williams, one of the Bills’ all-time first-round busts, was even worse at left guard, where he was given a shot when free agent signee Bennie Anderson continued to play poorly. Indeed, his struggles overshadowed those of fellow free agent Mike Gandy left tackle. Both have been yellow flag magnets. Rookie center Duke Preston might be an answer at either center or a guard spot, but it doesn’t appear either veteran Greg Jerman or sixth round draft pick Justin Geisinger will be any more than backups. But the Bills have to find out – about Losman, too – which is why the season’s final third is so important for Buffalo.’
