I'll pass. He bobbles a lot of catches, stumbles a lot, and would probably need years to learn route running. And this is assuming he has any innate talent for playing WR, which he hasn't shown yet (and Boldin showed right away). I get the appeal - he's a playmaker - but this guy has all the tell tale signs of being fool's gold. Watching him play WR is like watching a less talented version of Cordarelle Patterson. Anyone that takes him before day three is smoking crack, IMO.
I think Seattle is actually set up pretty nicely at WR anyway. Even if they lose Kearse and Lockette retires, the team still has Baldwin-Lockette-Richardson-Smith-Williams. I'm just guessing, but my gut feel is that Kearse's market is pretty soft and that he'll have more value to the Seahawks than other teams, so I think we'll see him back. That would give Seattle a very good six receiver group. Anybody Seattle does draft will be fighting for a 6th spot, which means that it probably won't be a high pick.
Don't get me wrong, I could totally see Miller as a Seahawk. He fits the MO. But I would be very surprised if they took Miller before the 5th round.
