Physics of a Dreadful Super Bowl

The Super Bowl was a real clunker.  If you are a fan of the Seattle Seahawks, you loved watching your team beat the Denver Broncos, 43-8.  If you are a Denver fan, you probably turned the game off at some point in the 3rd quarter.  For the rest of us who just wanted to see a competitive game, the Super Bowl was a real letdown.

Given that I wasn't on the edge of my seat with the action, I had a chance to look at the game with my physics cap on.  Below are some physics thoughts I had while watching the game.
  • The game started at 49 F, which was much warmer than the predicted weather when I contributed to a piece on a cold-weather Super Bowl.  Cold weather effects were thus minimal and not a factor in the Broncos looking like Elway's first three trips to the Super Bowl.
  • 9:45 in the 1st quarter:  It was 2nd and 7 at the Denver 39.  Demaryius Thomas caught the ball at the Denver 40.  Kam Chandler at 232 lbs made a monster tackle.  Execution was perfect as Thomas was knocked back 5 yards after being hit just a bit above his center of mass.  Imagine hitting a one-ton car going nearly 3 mph.  That's what the hit felt like for Thomas.  That 3 mph doesn't sound like much until you realize you're hitting a one-ton car!  In other words, you're not going anywhere!
  • 5:49 in the 1st quarter:  Russell Wilson faced 3rd and 4 at the Seattle 39.  He fired a pass to Doug Baldwin at the Denver 49.  The 10-yard pass took just 0.4 seconds.  Wilson fired the ball with an average speed of 51 mph, which is what was needed for the 1st down.  Wilson threw much harder, more accurately, and had a better spiral than the future Hall-of-Famer Peyton Manning.
  • 4:24 in the 1st quarter:  at the Denver 43, Wilson faced a 3rd and 5.  He threw the ball from the Seattle 49 while Doug Baldwin was just crossing the Denver 38 (the 1st down line, by chance).  Baldwin caught the ball at the Denver 20, meaning Wilson timed the pass to hit Baldwin 18 yards down the field from where Baldwin was when the ball left Wilson's hand.  The timing was perfect!  Baldwin made it to the Denver 6.
  • What I mentioned above is how Seattle dominated the 1st quarter.  Tackling was more fundamental, timing was better, and physics was utilized in ways that Denver could only dream of.
  • 12:05 in the 2nd quarter:  Seattle had 2nd and goal.  It was 8-0 at the time, when Marshawn Lynch got the ball at the 4.  He was hit at the 1-yd line, but the hit was off-center at his center of mass, which meant he merely bounced off the hit and into the end zone.  Again, poor tackling from Denver.
  • 11:24 in the 2nd quarter:  Denver was at their own 22.  Manning threw to his left to Demaryius Thomas.  The first hit was at the 24-yd line.  Byron Maxwell went below Thomas's center of mass, followed by help from K.J. Wright and Bobby Wagner.  The first hit stopped Thomas's linear momentum because the hit was just below the center of mass, thus creating just enough torque to arrest the motion.  Thomas was in trouble because as the help came, he had no forward momentum.  It was the perfect gang tackle.
  • Percy Harvin went 87 yards to open the 2nd half.  Harvin averaged 15.5 mph during his run.  He was speeding in a school zone!  His top speed was nearly 20 mph as he left Denver defenders in his dust.  Seattle won all phases of the game, most especially special teams.
  • 3:06 left in 3rd quarter:  Wilson hit Jermaine Kearse at the 17-yard line of Denver.  Three Denver defenders all hit Kearse at his center of mass, which meant Kearse just bounced off the tackles.  First, Danny Trevathan hit Kearse right in the center of mass, followed by Wesley Woodyard, and then Duke Ihenacho.  It was terrible tackling by Denver that led to Kearse scoring.  For some reason, Denver simply had poor fundamentals and poor physics in their tackling.
  • 2:39 in the 3rd quarter:  1st and 20 for Denver at the Denver 10:  Manning hit Wes Welker, and then Seattle's K.J. Wright hit Welker just below Welker's center of mass, ending Welker's progress immediately.  It was a textbook tackle and a perfect example of Seattle utilizing the principles of physics much more than Denver.
Seattle obviously dominated Denver, but I sat there as a physicist and marveled at how well Seattle's execution of play after play was consistent with what physics predicts for great football.  The physicist in me liked what he saw even if the game failed to live up to the hype!
