Eagle's rookies only started something like 2 games combined last year.
Well, Shawn Andrews would've likely started the whole season if he didn't get hurt.
But that was only due to Welbourn causes ruckus on practically draft day, forcing the Eagles to scramble to fill his spot. Likely they were taking Andrews originally to play backup for one year, then to step into Mayberry's spot this year with a year of learning under his belt to prepare him. I wouldn't be surprised if they use a 2nd rounder on an OT, just because they're planning on Runyan not being resigned next year.
I would agree though, that the Eagles first rounders have all been developmental players. Mitchell was a 1st rounder we threw all of 4 passes to in his first two years. Sheppard and Brown were the first two picks we took in one draft and spent practically two years on the bench. McDougle is another guy, we don't play too often (mainly from injury), but when healthy has only been used situationally yet, he's been in developement.
Having another pick 3 picks after their first rounder, I wouldn't hesitate to take Jones, the best athlete, who if he's a quick learner could possibly give them the one thing they lack (a solid #2 WR), or possibly replace Chad Lewis as another pass catching TE. He really fits their needs well, the question is, how long until you can play him? Which is why I think they trade up and grab Mike Williams, then let him learn from TO how a big physical WR gets it done at the NFL level.
Of course, trading up would cost alot, but the Eagles have extra 2nd and 3rd round picks, and Corey Simon to dangle at any team looking to trade down. Heck, with their 4 compensation picks, they can offer a good deal of 2nd day picks to sweeten the deal instead of Simon, who might not negotiate a cap friendly contract. With Miami in rebuilding, desperate for picks, same with Tennessee, who will likely need to cut someone just to sign they're #6 overall, the Eagles should have an opportunity to trade up and draft Williams, its just a matter of cost.
