Here are some notes at halftime:
Pittsburgh's passing game, for the most part, looks out of sync. Quarterback Ben Roethlisberger got hot late but for most of the first half he missed throws he usually makes. He underthrew a pass that was intercepted by Packers safety Nick Collins and returned for a touchdown in the first quarter. Green Bay's Jarrett Bush also jumped a route for a second interception. Roethlisberger threw for 143 yards, one touchdown and two interceptions in the first half
The Packers have done a good job of attacking Pittsburgh's second and third cornerbacks. Packers quarterback Aaron Rodgers is testing Pittsburgh's Bryant McFadden and William Gay and is finding success. Green Bay's first touchdown pass was a 29-yard strike to Jordy Nelson over Gay.
Pittsburgh struggled with injuries and penalties in the first half. Offensive tackle Flozell Adams (shoulder) and McFadden both suffered injuries but returned. Receiver Emmanuel Sanders also was hurt in the second quarter. The Steelers also committed four penalties that negated several good plays.
This might be the biggest test all season for Pittsburgh. This is the second biggest deficit for the Steelers in the postseason. The Baltimore Ravens led 21-7 at intermission in the divisional round.
