WHAT WENT RIGHT
* On their opening possession, the Seahawks gained a couple of first downs, and then ultimately faced a third-and-11 from the Pittsburgh 37-yard line. The Steelers blitzed both Lawrence Timmons and Ryan Shazier, but it was Cam Heyward who drove up the middle and sacked Russell Wilson for an 8-yard loss. Seattle punted.

• The Steelers took a 3-0 lead following a 12-play, 58-yard drive that began at their own 16-yard line and ended with a 44-yard field goal by Chris Boswell. Ben Roethlisberger completed 6-of-8 for 43 yards, and the Steelers converted 1-of-2 third downs to take a lead with 5:27 remaining in the first period.

• The second Seahawks' possession ended with a second punt. After gaining a first down on the ground, Seattle's drive stalled near midfield, and then on a third-and-4 from the Steelers 48-yard line, Lawrence Timmons' pressure and the fact his pressure contained Wilson along the sideline forced an incomplete pass and another Seattle punt.

• While the Steelers' special teams committed the turnover that set up Seattle's first touchdown, the kickoff return following the Seahawks first touchdown. Jacoby Jones' 36-yard return became 15 yards longer following a penalty for a horse-collar tackle on Jeremy Lane.

• From there, it took the Steelers seven plays to score their first touchdown and re-take the lead, 10-7. DeAngelo Williams rushed twice for 7 yards, and Ben Roethlisberger completed 2-of-3 for 24 more yards. The touchdown came on an 11-yard reverse by Martavis Bryant.

• The Steelers-re-took the lead and needed only 74 seconds to go 80 yards in eight plays, with the touchdown coming on a run by DeAngelo Williams. Ben Roethlisberger completed 4-of-6 for 72 yards on the drive, with three of those for 63 of those yards going to Markus Wheaton. When Roethlisberger completed the two-point conversion pass to Jesse James, the Steelers had an 18-14 halftime lead.

• After the Steelers defense forced Seattle into a three-and-out on the opening possession of the second half – Antwon Blake made a nice open field tackle on a quick pass to Fred Jackson on a third-and-4, Ben Roethlisberger went back to work. The official length of the drive was 78 yards, but because of sack yardage lost, Roethlisberger actually completed 6-for-6 on the possession for 84 yards. It ended up being a field goal when Roethlisberger's scramble on third downs came up 1 yard short of the sticks.

• After the Thomas Rawls touchdown converted the first Ben Roethlisberger turnover into a touchdown, Cam Heyward blocked the extra point. That kept the Seattle lead at 21-20.

WHAT WENT WRONG
* The Steelers got the ball first after the Seahawks deferred their selection until the second half. Their first possession found them facing a third-and-3, and Ben Roethlisberger went deep to Martavis Bryant instead of looking for something just to move the chains. Bryant was open, and Roethlisberger laid the ball into his hands, but it was knocked out by CB DeShawn Shead. The Steelers punted.

• It was going to be a 48-yard field goal attempt on the first play of the second quarter, but instead of Jordan Berry as the holder, the Steelers sent out Landry Jones. The Steelers then shifted into a formation that had Jones in a deep shotgun formation. On the snap, Jones rolled to his right and attempted a pass across the field to tackle-eligible Alejandro Villanueva. But Jones didn't get the ball over Jeremy Lane, who leaped to make the interception and returned the ball 54 yards to the Steelers 24-yard line.

• After the turnover, the Steelers benefitted from a post-play unnecessary roughness penalty on J.R. Sweezy that set up a third-and-goal from the 16-yard line. Even with that, Russell Wilson was able to find Doug Baldwin wide open over the middle for the touchdown that gave the Seahawks a 7-3 lead.

• Following the Steelers' first touchdown, Seattle responded with its best sustained offensive performance of the first half, with an 11-play 85-yard drive that had the Seahawks convert a third-and-10, another third-and-10, and then a third-and 16, before Russell Wilson hit Jermaine Kearse with the touchdown pass that put the Seahawks up by 14-10 with just over two minutes remaining in the first half.

• The offense's first turnover of the game was a mistake, not in the typical sense but in the fact the ball seemed to slip out of Ben Roethlisberger's hand as he was trying to pull it back. Ahtyba Rubin, all 325 pounds of him, made the interception and gave the ball to the Seahawks at the Steelers 37-yard line.

• Two plays later, it was in the end zone, but the first of those was an amazing catch by Jimmy Graham for a 36-yard gain to the 1-yard line.

• Roethlisberger's second interception shouldn't have happened either, but for a different reason. On an attempted long pass to Antonio Brown, cornerback Richard Sherman had his hands on the receiver and the receiver fell to the ground. Roethlisberger's pass then was tracked by Sherman, who made the interception and returned it 26 yards to the Steelers 39-yard line.
