Good Draft Equals Mediocre Season

I like the Eagles draft. I think the moves they made had them at the better end of the deals. The issue I have is a good draft for this team has nothing to do with the regular season this year. I like the offensive tackle they picked up from Pitt, but he won't see much action this year. I also have the feeling this means they still want to try out Winston Justice. Hopefully, they don't try him about against a good defensive end. Demps looks like a good weapon for Jim Johnson to use when Dawkins retires, but he isn't of much use immediately. Another small, fast end in the rotation may also not see much playing time, and he had academic issues. This worries me because Johnson's defense is not simple to pick up. Jackson will be used in the return game, but our special teams will be a question mark still. The blocking during returns was nothing spectacular last year. I'm figuring we'll have better coverage on kickoffs and punts with the free agent moves we made. We still have 4 corners on the team right now, so a fifth won't come into play (and I know the new guy is injured) unless we can get rid of Lito. I expect Laws to have an immediate impact and I know more penetration from down lineman helps, but that was not a major reason we were not successful last season. I'm curious to know if anyone else thinks the Eagles have done enough to compete in this revamped division next year.
