I'm pretty excited too.
What follows is only my opinion....
Maybe someone could beat Sherman and make a catch, but Seattle plays that cover 2. Sherman will have safety help over the top, or a linebacker underneath. Earl Thomas and Cam Chancellor are so good and versatile against run or pass that it's like Seattle has 12 men on defense. Seattle won't leave the back end open to allow Green bay to make those long runs after the catch.
Eddie Lacy needs to have a bigger day than M Lynch for Green Bay to win, and I just don't see it happening.
I like the Seahawks (-7.5) and the Over (>47), just like week 1.
