No, Garrett is back at CB. Lamur moved up to LB and I'm pretty sure Snyder said we were going back to more of a 4-3.
So if a guy that played SS is now called a LB, are we playing a 4-2-5 or a 4-3? 
Schematically the defense will be played as a 4-3 and not a 4-2-5 most of the time. Granted, we brought one of the safeties up last year as a 3rd LB, but the alignment and assignments are much different for the linebackers and secondary in a 4-3 compared to a 4-2-5. That's a big reason Garrett moved to CB, he simply didn't have the size to play up as the 3rd LB. Lamur did so he moved up to a LB spot. Plus the staff really wanted him to play LB last year, but he wanted to stay at safety.
This reminds me of the 3-3-5 talk during the Rich Rod Era, jesus christ I hated that defense.. I'm getting pissed off all over again just reading this thread, and it's a different defense and a team I'm totally indifferent towards..
I hated all the tweener guys that we recruited that never really found a position and just kind of ran around the field sucking, the 4-2-5 seems like a better design anyway, especially for the B12.. Plus, there are at least a fair amount of successful D's that run it as opposed to the 3-3-5 where it was us, WVU and a few mid majors that also sucked at D..
