If the Patriots could draft Matt Light or Sebastian Volllmer at #4 - given the other options in this draft - would that be worth it? I don't think anyone thinks that Jonathan Ogden is in this draft, but Campbell is pretty likely to come in and be the 10-15th best LT in the league for a decade. And if not, he's likely Logan Mankins with the ability to kick out to OT in a pinch. In this draft, I'll take that at 4. There just aren't any slam dunks.I'd argue there's not a ton of difference between the '1st' rated tackle and the '6th' rated tackle, and none of them are worth Pick #4.
Ersery has a higher ceiling, but isn't anywhere close to being a sure thing.
