None of the picks really bother me.
When I look at Staten's limited tape I see glimpses of what Red Bryant was prior to 2010. I also see similarities in both thier length, strength, big body and athleticism.
Staten's a leader and looks to have a good head on his shoulders to give everything he's got especially coming from a small school where this is probably an opportunity of a lifetime for him.
Like you said he might not make the practice squad but he'll compete, he'll make the guy in front of him better, and that guy in front of them, will make the guy in front of them better and so forth.
So, let them compete... not much downside looking at the bigger picture.
#11 is the Gatling Gun, coming at Ds in multiple, unpredictable ways spreading the field horizontally.
#10 is the Sniper Rifle, if you don't respect his deep field speed opposing DBs will end up in a pink mist.
#24 is the Boomstick, get in his way when you're the lone defender, I dare you.
