When your starting running back averages six yards per carry, you do what you can to get him the ball.
"It's real simple," Hackett told WGR-AM on Wednesday, via The Buffalo News. "We're going to give him the ball until he throws up. So he's either got to tap out or throw up on the field. Let's just put it that way."
Hackett isn't concerned about sharing that strategy with opponents: "It doesn't matter," he said. "You can say that because any team that has ever watched him should, I mean ... You've got to stop C.J."
Hackett's words are a sweet melody to Bills fans, who sweated through coach Chan Gailey's awkward, stop-and-start use of Spiller last season. The third-year pro averaged just 12.9 carries and 2.7 receptions per game, but he still piled up 1,244 yards rushing on just 207 attempts.
Hackett doesn't see teams taking a stack-the-box approach because of the Bills' "awesome weapons on the outside." Still, Spiller remains the focal point of defenses hoping to neutralize the Bills' offense. Twenty-one backs had more carries than Spiller one season ago; that won't be the case in 2013.
