'Bills TEs/RBs vs. Denver LBs: Denver's linebackers had a lot of trouble covering backs out of the backfield last season. The Bills should test to see how much they've improved. Inside backers Todd Davis and Brandon Marshall return from last year. Strong side outside backer Shane Ray (8.0 sacks) is out with a wrist injury. His stand-in, Saquil Barrett, has looked good the first two weeks. He entered the NFL as an undrafted, Steelers-style stand-up rusher. What about the rest of his game? It will be interesting to see who Denver opts to keep on the field to defend LeSean McCoy.'
