I agree, smokescreen.
Plus, guys like Armando who report that Dolphins are high on a tackle and will trade up for him are just being part of the team, playing the game, to get the communications out there the organization wants. There's absolutely no chance, imho, that Hickey trades up for an O lineman. If he trades up, it will be for a different player. But since this is a year we need to pick up both a tackle and guard, doing that is not probable, because he'd lose a high draft pick. So he'll either pick the best player of need at 19, or trade back a few spots.
