The Eagles drafted DT Mike Patterson in the first round last year, but feel they still need another inside guy who can collapse the pocket and defend the run.
They upgraded themselves on the weak side with the signing of Shawn Barber, but need to do better than Dhani Jones, who was awful at the point of attack last year and failed to slow up tight ends.
One starting tackle is coming off of major back surgery. The other is 32 years old. The center also needs to be replaced.
Brian Dawkins is 32 and appeared to have lost a step last year. He's got one year left on his contract and there is no viable replacement on the roster.
