IMO, there are only two free safeties worthy of a pick before #21 in the third round in this class.
There's Clinton-Dix. He'll be long gone before the Packers are on the clock. To get him, Ted Thompson would have to trade into the top 15, and there's a good bet he'll be gone in the top 10. If he fell to 21 I'd be ecstatic and I'd send the card up in seconds.
But that's just dreaming, IMO. There are dumber GMs in front of Ted Thompson in the draft order, but there aren't 20 who are going to let Clinton-Dix pass. Ain't happening.
Number two is Pryor. IMO he's early second quality, but I understand why most think of him as worthy of #21. He might be there, so that's a possible choice.
After Pryor....I might take the guy from Stanford (if there weren't some injury concerns) in the third.). Personally, even that's a major reach.
And the rest of the draft class? late 5th at best, IMO. Either they have speed issues, or they take bad angles regularly, or, worst of all, are bad tacklers. And most of them have two of the three problems. The three problems that have plagued this team at the safety positions for years.
Strong safety? You've got Bucannon, who everyone seems in love with, which I don't get....before the third is a reach. And you've got Ward, who isn't worth a first but will be long gone before the 21st in the second. And you've got Dixon, who is probably early fourth level, but I would be willing to stretch at 21 in the 3rd. And Loston maybe. I like Berhe, but he's a late 5th, just like all the rest; unlike the rest, he doesn't approach tackling like he's channeling Darren Sharper or the "tackle by throwing a shoulder at someone as hard as you can" school.
IMO if you want to get three third-round-or-better safeties in this draft you are going to have to spend the rest of your draft choices trading up (and probably next year's first as well, if you want Clinton-Dix).
I wish it were otherwise. I wish I had someone in garters and heels sitting in my lap right now.
But it's no more likely to happen.
And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.
