‘Losing Pro Bowler Williams to a foot injury after just five games rocked this group, and it never really recovered. No. 1 pick Dareus started at end and then moved inside in the team’s 3-4 base look after Williams was injured. Dareus finished with 43 tackles and a team-leading 5.5 sacks. He figures to be a fixture up front for years no matter the scheme. Williams is on schedule for a return in 2012. Other than those two, Buffalo could use upgrades at both end and tackle. Edwards contributed 52 tackles and 2.5 sacks, but meaningful plays were few and far between. The Bills had just 29 sacks and allowed a team-record 5,938 yards, so there is much work to be done in the front seven.’
