From Seattle's defense? I know nothing about them except that their secondary is tall. I couldn't tell you 1 name on Seattle's defense. Except for Earl Thomas.
In terms of Seattle's defense, the thing that makes them so tough is because their 4-3 defensive line has the bulk and space eating ability of a 3-4 defense(3 out of the 4 starting d-linemen are over 320 lbs). Also, one of their DE's Chris Clemons had 11 sacks and 3 forced fumbles last year.
So despite everyone saying I'm a troll, I expect a good, hard fought defensive battle. Hopefully the Seattle defense lives up to their top 10 ranking that they earned last year.
