Yes, this game has the early markings of an upset. A fumble by the Pack on the opening kickoff setting up the Lions for an easy score. Then the Packers march down the field on a double-digit play drive only to stall out at about the Lions' 25-yard line setting up a 43-yard field goal attempt by Mason Crosby...which he misses wide right.
As the announcers said, it appears the Lions are the 6-4 team rather than the Packers. The only redeeming features of the 1st quarter was a great sideline interception by Nick Collins at the Pack's 26-yard line as the Lions were moving the ball, and a 68-yard toss from Aaron Rodgers to Donald Driver to end the quarter and put the Packers at the Lions' 7-yard line.
As anticipated, the Lions have come out on fire. The Packers, not so much...which is usually what happens when a turkey-size egg is about to be laid.
