Mike Sando har et langt, bra sttykke om nettopp det temaet på Espn idag.
Dominance in perspective
Since 2011, when Sherman joined a Seahawks roster already featuring Thomas and Chancellor, opposing quarterbacks have gone from being historically bad against a fully equipped LOB secondary to quite respectable when one or more of them come off the field.
Opposing quarterbacks have 83 touchdown passes with 109 interceptions on plays when Thomas, Sherman and Chancellor were all on the field together. This period spans 94 games and 2,869 pass attempts since 2011.
The numbers lend themselves to comical application. Seattle with those players on the field has allowed the following passing numbers on those 2,869 attempts:
59.4 percent completions, same as the career rate for Seneca Wallace
6.4 yards per pass attempt, same as the career average for EJ Manuel
2.9 percent touchdown rate, same as the career rate for Mike McMahon
3.8 percent interception rate, same as the career rate for Rex Grossman
71.2 passer rating, worse than the career rating for Luke McCown (71.3)
40.1 Total QBR, same as the career figure for Mark Sanchez
Put another way, the Legion of Boom has, on the whole, rendered all the quarterbacks it has collectively faced to become indistinguishable from those journeymen.
Remove Thomas, Sherman and/or Chancellor from the field, and the numbers over the same time period (since 2011) flip. Opposing quarterbacks have 41 touchdown passes with 17 interceptions on those plays.
The composite quarterback with numbers approximating those that opponents have put up against these incomplete LOB backfields averaged:
6.9 yards per pass attempt, same as the career average for Matt Hasselbeck
3.9 percent touchdown rate, same as the career rate for Alex Smith
1.6 percent interception rate, lower than the career rate for Tom Brady
89.2 passer rating, same as the career rate for Andy Dalton
58.7 Total QBR, about the same as the career rate for Carson Palmer
That's a big spike in opposing quarterback production when one of those LOB stars leaves the field. This game against Atlanta on Monday night will mark only the seventh since 2011, counting playoffs, in which Seattle has played even a single snap with Thomas on the field while Sherman and Chancellor are off it. That includes only 11 pass attempts over the past four seasons and zero over the past two.
