i dont think its flipping back to slower bigger guys, more that there are more players coming through who have both range and the physicality/want to to play higher in the box because college schemes dont want the rangiest defender to be stuck playing single high so these guys have to be able to play close to the LoS
jamal adams isnt a slow player nor is he that big but he's someone who is good on the backend but is also a playmaker close to the LoS both in the passing game and the running game
and its interesting that weddle gets mentioned (and Earl Thomas now) because those are guys we think of as free-safeties and yet look at what we ask them to do in the ravens scheme... it's not that dissimilar to what jamal adams etc are asked to do
