'Fans tend to disparage this unit, but McCoy, Karlos Williams, Taylor and Gillislee weren’t the only reason Buffalo led the league in rushing. Center Eric Wood is coming off a less-than-stellar year, but is solid as is the left side of the line — guard Richie Incognito and tackle Cordy Glenn — both of whom signed generous contract extensions. Right guard John Miller struggled a bit as a rookie and the right tackle spot is a contest between Seantrel Henderson, fresh from a bout with Crohn’s disease, and veteran Jordan Mills. In reserve are center Patrick Lewis and guard Ryan Groy.'
