‘The Bills’ offensive line will be challenged by the Patriots’ interchangeable ways Sunday when the teams meet in Buffalo. The Bills’ line consists of left tackle Jonas Jennings, left guard Lawrence Smith, center Trey Teague, right guard Chris Villarrial and right tackle Mike Williams. Jennings, Teague and Williams are returning starters, while Villarrial was a top free-agent acquisition and Smith a first-year free agent signee. Leaky offensive line play (NFL-high 51 sacks in 2003) has been a concern in Buffalo in recent years and the well respected McNally, a 25-year NFL coaching veteran hired by first-year coach Mike Mularkey, is being counted on to help fix it.’
