I personally think it's the safeties our staff doesn't trust in space.
I would agree. Hopefully CJax can respond well next to Coop.
I really think our safties are - overall - our weak spot. I think that was probably even our weak spot last year, which is saying a lot. Yes, we were fairly bad on the line - especially after Stein got hurt - and our LBs were spotty at best. But I think average safety play would have cut the number of big plays in half over the last year-plus.
Also, I'm really not sold on Cooper, either. Yeah, he at least makes some plays - which HJax really hasn't so far - but he's looked like the second coming of Damian Stafford so far: for every one good play there are two or three where he takes a terrible angle and doesn't even touch the ball carrier.
