The Seattle Seahawks beat the Denver Broncos 26-20 on Sunday afternoon at Century Link Field in an overtime nail-biter.That’s right, four quarters wasn’t enough to contain Sunday’s much-hyped game against the Broncos, the first regular season match-up between the two teams since Super Bowl XLVIII. But for most of the game, OT hardly seemed like a possibility, let alone a probability.Missed opportunities for both teams led to a disappointing 3-3 tie at the end of the first quarter. Seattle came alive in the second quarter, with QB Russell Wilson throwing two touchdown passes to Ricardo Lockette and Marshawn Lynch, respectively. The scores put Seattle up 17-3 going into the half, a lead that stuck through an uneventful third quarter.But the wheels started coming off for Seattle early in the fourth. Not even three minutes in, Wilson wound up sacked on his own one-yard line for a loss of seven. The sack set up Lynch to get mobbed by Denver defenders in the end-zone for a safety, cutting the Broncos deficit to twelve.Only two minutes later a deflection on a Wilson pass sent the ball into the hands of Denver’s Chris Harris Jr instead of Percy Harvin. Denver didn’t miss the opportunity to capitalize on their good fortune. A three-yard shovel pass from QB Peyton Manning to Julius Thomas resulted in a touchdown to complete the drive, narrowing the Hawks’ lead to only five. It seemed the horse was finally tamed late in the fourth, when Seattle safety Kam Chancellor intercepted a Manning pass intended for Wes Welker. Seattle converted the subsequent drive into a field goal, giving the Hawks what felt like a comfortable 8-point lead.But Manning wasn’t done. The veteran quarterback showed he’s still got it, orchestrating a precision-guided 80-yard drive in the last minute of regular play. Manning connected with Jacob Tamme on a 26-yard pass to the end zone with under 30 seconds on the clock, following it up with a successful two-point conversion pass to teammate Demaryius Thomas to improbably tie the game 20-20 with 18 seconds left on the clock. Seattle elected to take a knee after receiving, and into over-time we went.Seattle mercifully won the coin toss, electing to receive. And that’s when the fun began. Wilson, who’d been reluctant to deploy his trademark scramble in regular play, ran for 21 yards of the 80-yard drive. Completions to Harvin and Kearse kept it alive, along with key runs from Lynch. And indeed, it was Lynch, in full beast-mode, who clinched the win, running for six yards into the end zone.Check out our slideshow for all the game-day action.
