When considering the
last two pieces of conventional wisdom, the Seahawks home field prowess and
their inability to win morning games, we looked at win percentage and point
differential for the whole sample set. For the analysis of these narratives the
holistic view of the sample set worked because the conventional wisdom only
considered their ability to win or lose. So for the idea that the Seahawks are
dominate in the evening we need to look at more than just winning percentage
and points scored in all evening games. Although the Seahawks do have a great
winning percentage at 83% (15/18) win by an average of 12 points per game (ppg)
this could all be fueled by poor competition. If the Seahawks are getting to
play the dregs of the league every time they play a primetime game they could
easily be running up the score, but it doesn't mean they are dominate, just
that they are playing bad teams. To try and understand if the Seahawks are
dominating their opponents I decided to take a look at their opponents final
winning percentage over all 16 games and see how they did against good teams
compared to mediocre and bad teams.
Between 2010 and
2015 the Seahawks opponents in evening games have had an average seasonal win
percentage of 56%. To say this differently, during the season that their opponents were forced to play the Seahawks on primetime those same opponents won over half of their regular season games. So the Seahawks opponents are on average
good, but not great. A 56% win percent is equal to 9 regular season wins.
We can break the
Seahawks opponents into two categories: good teams, and mediocre and bad teams.
Against teams with less than a 63% win percent the Seahawks are undefeated
going 8-0. Against teams with a regular season win percentage of 63% (10 wins)
or more the Seahawks have only gone 7-3. The Seahawks are undefeated against
the teams they should beat (the mediocre and bad one) and they are consistently
beating the ones that should be more evenly matched against (the good ones).

So, the Seahawks are
winning lots of games on MNF, SNF, and TNF, but are the winning big? Are they
truly dominating the competition? Are they running up the score against bad
teams and just barely squeaking by against the good ones? To figure that out final
point differential, the difference between the Seahawks and their opponents
final scores, is a perfect stat. We can also break point differential down into
the same two camps: good teams, and mediocre and bad teams. As mentioned before
the Seahawks are outscoring all their opponents by an average of 12 ppg.
Against good teams, those with over a 63% regular season win percent, the
Seahawks won by an average of 12.1 ppg. Against mediocre and bad teams, those
teams with less than a 63% regular season win percent, the Seahawks won by an
average of 11.9 ppg. Basically the Seahawks are beating opponents on primetime
by almost two touchdowns regardless of the quality of that team. The Seahawks
are the definition of domination.
The final piece of
conventional wisdom related to the Seahawks that needed to be investigated for
the Pete Carroll era was their dominance during evening games. The Seahawks
opponents were be broken up into two different groups, good teams, and mediocre
and bad teams, based on those opponents regular season win percentage. Then the
Seahawks win percentage and final score differential against those groups were
examined. During primetime the Seahawks have won 70% of their games against
good teams by an average score of 12.1 ppg. The conventional wisdom about these
games is still true, the Seahawks are dominating their opponents during evening
games. Under Pete Carroll the Seahawks are a dominate force in primetime.
