This isn't the Reds.Probably not, but see what you have in Dax Hill. Safeties should be low on the pecking order in terms of importance to the team.
The Bengals expect to win championships. You don't "see what you have" in a guy if you expect to win. Especially if you can afford a proven player.
As for Dax Hill.... he couldn't get on the field as a 1st round pick in a banged up secondary. I'm guessing the Bengals know what they have in him and it ain't good enough. Maybe he'll get better but that's a stupid risk to take if you don't have to.
