'From a two-back run game perspective, the addition of Jerome Felton gives Roman the flexibility to incorporate some power plays from a variety of heavy or jumbo sets, with McCoy aligned at tailback. During Felton's time with the Vikings, the hammerhead fullback paved the way for Adrian Peterson with his aggressive blocking at the point of attack. He uprooted linebackers out of the hole and routinely sealed the backside on cut-back runs for Peterson. Felton will have an opportunity to do the same for McCoy when Roman employs the two-back power running game from tight formations. Given McCoy's previous success finding creases in traffic, providing him with a lead blocker could produce fireworks for the Bills.'
