They got in a big debate over these two on /sp/ and someone did the homework to shut everyone up. But then they were talking about who played who, so someone did the next bit of homework and found out that Wilson went up against harder defenses too.
>49er's previous opp's: NE, MIA, STL (x2), NO, CHI
>Seattle's previous opp's: MIA, CHI, ARI, BUF, NYJ, MIN
in passing defense:
>49er's opponents: 29th, 26th, 9th (twice), 31st, 6th
>Seattle's opponents: 26th, 6th, 4th, 15th, 2nd, 23rd
Wilson has slightly better opponents while facing an average of the 13th best pass defense, while Kaep is slightly worse while facing an average of the 18th pass defense.
Im liking the stats. Math is never wrong.
