the idea of free and strong safety has become a bit archaic, really.
Also true. Having 2 players of Bush and Carter's skillset and caliber allows for either to assume whatever role in the defense is needed on a given play.
Considering how the spread and complex passing games has changed football at all levels, the idea of safeties needing to be more well rounded has never been more important. Attacking and exploiting safety play is what offenses do now in the passing game. Nearly everything an offense does in the passing game is looking to exploit safeties and getting them to **** up or be even a half step out of position.
As we've discussed in the past, what this does is mitigate the importance of superstar athletes and actually gives more value to "headier" players. However, this happens a lot more in the NFL than in College.
Its more obvious in the NFL because the QBs can make the throws that need to be made and the pass catchers are better equipped and coached up to run the complimentary routes that make those plays work.
Gomer Manning will become one of, if not the GOAT at his position, because no one was better than turning safeties into puppets. At the college level, the QBs by at large can't hit the soft spots between the safety and corner outside the hash, there aren't a ton of TEs that can run the seam or even asked to do so, and wide outs aren't equipped to run the complimentary routes with precision like they need to be.
