Why not another Corner in the 1st?

I don't understand why not one is talking about taking another cornerback to pair with Hargreaves? Do people really want to keep Grimes out there until he loses a step and is getting burned all the time? I think most will be gone by the time 19 rolls around but I'd rather take someone like Adoree than McCaffrey at 19. Who is your favorite corner for the Bucs and would you take one at 19?
