Nice write-up, k9, but the reason our Safeties (and everyone else you mentioned on D) suck is because of the corching. It's impossible to have so mainly highly recruited guys that everyone in the country wanted all coincidentally be busts who can't play. Is it easier to tackle a rolling soda machine like Abdullah The Butcher if you can get a couple hats on him early than it is when he has 7 yards to get a full head of steam before he's touched on any play?
You were very tough on the players in this write-up, and I just don't think that's justified given the corching constraints. Any team in the country would have been elated to have signed guys like Carter and Bush at Safety.
I think the criticism regarding safety is fair. I think we need more speed and range from the position. That said, Bush actually fits the mode of what you're looking for in a modern day safety. Someone who is a former high school cornerback, capable of providing solid deep coverage and good tacking ability in space. And although he's struggled with the latter, I do agree that it is asking an awful lot of him to be a force player when aligned at 15 yards (if that's actually the case). So, yes, there are some coaching constraints which need correcting.
When Carter signed with UM I thought he would make an outstanding SLB. In Miami's traditional 4-3, he would give you solid coverage (a former safety and space player), especially when detaching from the box against a slot receiver (zone coverage). With Carter at SLB there's enough speed at OLB where you could actually play base against 2x1 sets.
We just need more speed in the back seven. It's there. I know speed isn't everything, but you simply can't teach it. Safeties running 4.6ish? Man, historically, that's below average linebacker speed at UM. At least it use to be. Heck, we've even had some DLmen who actually ran 4.6ish.
I think Burns at safety would be interesting. I like the idea. I also like Gunter there too. If nothing else, it would be an instant upgrade in terms of speed and coverage ability. JMO.
