I understand the logic of getting a LT that can play for a smaller cap number and has less miles. But to me it's a wasted pick. We have a fairly young LT on this roster already who is proven. There is no sure thing at LT, I'd be happy to list some busts if need be. As far as getting him at a cheaper price, this team doesn't have cap problems. They are perennial cheapskates and are consistently one of the teams with the most cap space every offseason. To me you are choosing between Matt Cassel and Joekel or the best QB available plus Branden Albert. I will take the latter. I understand we could sign or trade a QB other than Cassel to play with Joekel. But we could do the same thing and have them play with Albert. Use the #1 draft pick to upgrade your team. Joekel is not a meaningful improvement, if any at all over Albert in other way other than money. You franchise tag Albert and make him prove he's healthy. If he is healthy, then sign him to a contract during the season.
Im also not a huge fan of giving up our 2nd rd pick for Nick Foles. I'd rather take a flyer on the 2nd or 3rd best QB available in this draft that will still be sitting there when we make our 2nd selection. Or packaging our 2nd and compensatory to move back up into the late 1st to grab the best QB available. Foles is not worth a 2nd rd pick in my opinion. Nothing more than a 3rd and would think you could get him for a swap of 3rd's and a 4th rd pick.
I like your other thoughts at safety and lb. I like Jared Cook but I thought we had Boss back for another year. I could be wrong though.
I just have a very hard time understanding how using a once in a couple of decade pick(#1 overall) to upgrade a position of strength helps our team more than addressing the biggest weakness on this team. Joekel with not be a better LT next year than Branden Albert IMO. Lets take a shot at a QB big he doesn't work out, then you take another shot at one next year. And you repeat that process until you have found your qbotf. Then you build around him.
Hopefully you realize that letting a good LT walk(Albert), just to spend 3000 draft points on a new LT is the equivalent of drafting a bust QB with the #1 pick. At least if we draft the best QB in the draft there is a chance he won't be a bust. Or at the very least draft a position of need. Sign Bowe, tag Albert and due your homework on the QB's.
