I agree almost completely with your classifications. Only differences I may suggest: I think CJ Wilson would definitely be in the "Run Stoppers" category, as I don't think he offers anything in the pass rush department (for the most part). Exact opposite for J. Wynn. He's supposed to be more of a pass rusher, but isn't very stout against the run. Unfortunately, neither of them are very good at what they are more than likely "supposed" to do best, so I can understand why you put them where you did.
I think I would classify Neal more as a pass rusher as opposed to both. Although maybe he will never regain the burst he once had in time for the Packer's to see. He's strong, but I think his aggressive style of play will lead to below average run defense. If he wants to be a good run defender, he will need to play more disciplined (although first, he'll obviously have to stay healthy.
I also think Worthy would be more of a pass rusher as opposed to both at this point, but I'll have to see him more to be able to say. I think he can be a good run player, but his quick first step and explosiveness make him an overall much better pass rusher . . . at least from what I saw of him in college. He will also likely have some difficulties in playing disciplined at times due to his aggressive "gap-shooting" style of play. I think it will be more a matter of coaching and learning that decides what type of player he will be, because the talent in there to be an all around beast.
