We "need" our pass rush to step up, but on offense, I'd like to see Richardson step up.
We need to take the top off of defenses so they not only quit stacking the box, but creeping up in the box and condensing it.
In theory, Harvin (with his elite acceleration) would be a great blitz beat on a quick slant, but evidently he didn't want to do that. Richardson, with his speed, should be able to do the same thing. His routes looked very polished in preseason, and he's not a 1 trick pony. Having Richardson on the field, and having teams respect his speed, will help us beat blitzes.
We really need to throw a few up to him, even if they're incompletions. So far this season, the Seahawks haven't really challenged anyone deep. Teams need to know we're going to hit them over the top.
