First off, it is great to read your stuff again man. I think you and I had the same initial reaction to the move up, but I am less down on it than I was a few months ago, and here is why:
1) Wentz is not as risky as folks think. Right wrong or indifferent he was projected to be a top 10 pick at QB from about the middle of the season on through. After the Senior Bowl he never left the top 5 of anyone who had half a brain's mocks, and it would appear from the incredibly limited information out there that he was a top 10 on pretty much every team's board. So what? Well.....QBs picked in the top 10 have an over 70% chance of being a multi-year Pro Bowl selection. "But Rick Burlesons Yam Bag, he played at a school smaller than one of your poops, and the act of being selected doesn't MAKE him a multi-year Pro Bowl Selection" you may say. And you would be right. I literally took a deuce that was bigger than NDSU after a rough night of burritos and beer about a month and a half ago. Also, he was not a 4 year starter, which is not a great sign. However, he was a straight A student with no off-field incidents and he was on a team that won the national championship for 4 straight years. This is a lot different from other QB situations where guys fly up the board based on 2-3 games, or a great workout. While injury is always a dice roll, the various stats (I have only cited the top 10 draft and games started, but there are lots of completion % stats et al on the various Eagle nerd sites) seem to indicate that he is more likely to succeed the way we need him to (top 10 QB for 3-5 seasons) than not. Goff is even less likely to fail.
2) First round QBs are insanely valuable. Duh, right? Not only have the passing rules changed so that farting in a receiver's general direction is a 73 yard penalty, but with the salary slotting in place, and with the 5th year option a legit thing, first round QBs are basically the best value in the market if they work out reasonably well.
3) The Eagles crapped on themselves - and it may have worked! In a vacuum, the Bradford and Daniels deals look terrible. However, if you look at them with the lens of "developing Wentz" they begin to make sense. Bradford is an absolute injury risk who can't be trusted to stay on the field for 16 games, so his deal is basically a one and done with Daniel backing him up. Wentz is almost certainly on the McNabb plan, which means that he won't sniff the field until after Thanksgiving, they needed to have two decent starter-capable guys in front of Wentz. If Bradford has a halfway decent season, the Eagles can trade him for a draft pick, there will be the same number of teams desperate for a starting QB next offseason as there was this season.
Let's see. They have to play actual football at some point and to your point, if Wentz gets his knee blown up in his first start then the Eagles are in the toilet for a good few years. But in the grand scheme this deal is better than drafting Danny Watkins, and I am kind of interested to see how Pederson, Schwartz and Reich put this all together.
