I just can't get on board with this possiblity, and I am more than a little surprised at the level of support it seems to have. Holland's play has declined since his rookie year and he is known to have nagging injury issues. Safety is not a position where it makes sense to have a premium investment, especially after using a 2nd rounder just last year. This isn't Ed Reed in his prime or some sort of outlier.
I am fine with a more affordable free agent option or mid round pick and let that person compete with Rapp and Bishop. Under no circumstances should Hamlin have a role, even as a backup. That experiment needs to end. He was, along with Elam, the worst player on the entire field in the AFC Championship game.
