'Hughes' sack production in 2015 wasn't great, registering only five for the Bills last season, but he put much more pressure on the quarterback than that number would indicate. This year, Hughes is no longer shackled to one side of the field, as he has been for the majority of the last three seasons. Over that time, the Bills usually kept Williams on the left side (against the right tackle), with Hughes on the opposite side versus the left tackle. That is, until around the middle point of last season, when the Bills started using Hughes, not Mario, as their matchup problem versus below average offensive tackles.'
