I disagree, if he's a starter it's worth a 3rd-4th pick swap. And that's if he's mediocre.
A good starting Tackle is worth more than what they gave up, maybe a lot more.
It's a gamble for sure because he looks like a pretty flawed player. But it's a small gamble because it's only dropping down a round in the middle of the draft.
Especially if it's a strong draft like people are saying. They might still get a 3rd round caliber player in the fourth anyway.
I don't understand why some people (not you) are frothing at the mouth over this. Even if it doesn't work out it's fine. The biggest issue if it doesn't work out won't be that they lost a little draft compensation, the biggest issue will be a problem at
Tackle. If nothing else at least this is a reasonable attempt to solve it with a pedigreed player.
