Ok, boy there's a lot of comments I want to respond to, so I'm just going to break it up by paragraph.
Concerned about the Eagle's secondary? Not I. I watched them all season, with Vincent, Dawkins, and Taylor barely playing at all. Let me tell you, if the Eagles have depth anywhere, its in the secondary. The backups stepped up all season long and proved that there were people in the organization capable of replacing Vincent and Taylor. So long as Dawkins keeps hitting people like a mac truck the secondary won't miss a step.
As for priority. I hope Reid realizes a good chunk of that left over cap has got to a WR. Drafting even Larry Fitzgerald wouldnt fix the WR problem in Philly. Thrash and Pinkston need to be cut, plain and simple. Brett Favre in his prime could not throw accurate enough to make these guys catch consistently. Darrell Jackson, even Tai Streets, would make a significant impact for certainly a reasonable price and take some of the offensive pressure off of McNabb.
As for Kearse himself. I read someone state he's been consistently lame, then provide the statistic that he had 36 sacks in 3 seasons (over half of his career). Sounds to me like he just had a pair of bad years, especially considering the games he missed during that time. I bet in another full season he'll register another dozen sacks. I would be concerned about his health, but lets face it, the Eagles got him b/c of health concerns on their defensive line. They're not going to pay top dollar for someone who isn't likely to solve their worries about another injury riddled line, so Kearse is either a vary saavy and convincing businessman, or he's reasably healthy, and prepared for a full season of terrorizing QBs. Kearse is also young too, so he may just have a 2nd wind in him, whereas in other times I've seen philly teams bring in big names past their prime: The fridge, Paul Coffey, etc.
I assume the Eagles know they have a WR problem to fix, and so I dont even worry that they'll take care of it. My major concerns would be what they plan do to at RB (Westbrook has the skills to be a featured back, but can he endure the beating?), and how they plan to fill the void left by Carlos Emmons at LB.
