I like what I heard from Castillo in the Missanelli interview.  I believe he will get the absolute best out of the guys on D, which our previous coaches didn't(Jason Babin anyone ?) 

Castillo isn't the smoothest speaking guy but how many positional coaches and football players in general are ? Its X's and O's, not brain surgery.  Once we get some decent LB and secondary coaches to help with the intricacies of those positions, I think we will be OK. I know everyone would have wanted a schemer like capers or lebeau(or one of their proteges) but the eagles have a VERY young team overall. Picking up advanced schemes may just hurt these guys ability to just REACT. Instead of playing balls out they are thinking too much.  All of our draft picks come in as guys who can run, hit and jump on the same level as most of the peers in college. Some coaches are able to take that raw talent and make it into something great when they are young in their career and as they get older they pick up the mental part of the game. Castillo may not be the best at making on the fly game time decisions(nobody knows, yet), but if your players don't understand your scheme and aren't fundamentally sound I don't think it matters nearly as much.
