Neither Dye nor Parrish move the needle for me, but adding a back through the portal makes a lot of sense for depth purposes.
Parrish reminded me of Yearby coming out as a low ceiling player without next-level tools but if he does come to Miami via the portal, as appears to be expected, then hopefully he does well with his opportunities. He should be serviceable as a role player.
I'd be excited about a full season of Chaney and Knighton as the 1 and 1A (or vice versa), but Chaney's health is unfortunately the big question mark. Mario's smart to be seeking added depth for the RB room.
