Although the Lions offensive line has yet to give up a sack this season, Matthew Stafford was hit six times last week, including four shots by Chiefs OLB Tamba Hali. ESPN analyst Mark Schlereth found fault with LT Jeff Backus when breaking down film. "Don't let stats get in the way of facts - don't let them get in the way of your eyeballs," Schlereth said. "There still are some concerns with this team when it comes to pass protection, and I have concerns about their left tackle." Backus squares off against Vikings Pro Bowler Jared Allen this week.
