My comp for him is Patrick Peterson. While he doesn't have Peterson's overall size, SG is 194 to PP' s 219 coming out.
I see similar use of elite athleticism, track backgrounds on thier games.
Griffin like a young Peterson is going to give up plays because the instincts aren't there yet, but the athleticism will help him be a play-maker.
And I like Griffin in this system, with our coaches, expectations, if he can develop his instincts and techniques in the Seahawks way, he'll have the tools to be a top-tier corner someday.
