He's a hybrid DB just like Byron Jones is. However, I think you can put Ramsey at SS and Jones probably doesn't fit there if you need to do that. That gives you a tremendous amount of flexibility in the defensive backfield. If a corner gets hurt, you can move him there. If a safety gets hurt, you can put him over there. You can essentially field your best 4-5 players in the defensive backfield far more often.
He's a player that can defend a big TE like Gronk, a big WR like Alshon Jeffrey, speedsters like Antonio Brown and quick slot guys like Cole Beasley and lock them down.
I think Byron has those capabilities as well, but with two players like that in the defensive backfield you're shutting down high profile passing offenses with either guy being able to lock on the top 2 pass catches from the other team. And if one of them gets injured, you still have that versatile player than can lock on the top receiver of the other team.
He's also an elite athlete as shown by his SPARQ score and he tackles well.
He's never said that he doesn't want to play safety. And scouts have said that they think he could be an All-Pro corner. Plus, Mike Mayock, who has a good history of judging DB's, raves about him.
Meanwhile we have EE who can only play 1 position, he has a mediocre SPARQ score and the position he is playing has a high rate of depreciation.
