‘Denver QB Tim Tebow is the main attraction, but stopping RB Willis McGahee from getting traction will be Buffalo’s first goal. McGahee (206 carries, 990 yards, four TDs) powers the NFL’s No. 1-ranked running game that averages 163 yards per game and takes pressure off Tebow. Of course, the multi-talented QB is also a terrific runner, complementing McGahee with 610 yards and another six scores. Buffalo’s run defense has fallen to 29th in the league after giving up 200-plus yards to Miami’s Reggie Bush. If McGahee and Tebow run wild, this one will be over before it starts. Offensively, the Bills’ offensive line will need a big game against one of the NFL’s best pass-rushing teams with 36 sacks. Struggling QB Ryan Fitzpatrick leads the league with 19 interceptions and could crumble fast under a Broncos’ onslaught.’
