I find all of those players speculated upon to be in real trouble to make this roster.
Kuhn you can see, with his advancing age, higher salary, diminishing effectiveness as a lead blocker.
Bush you can see, as he is climbing up there in age as well, and has proven to offer little in the secondary on a consistent basis. He has stayed on this team by being a STs star. He may be the toughest call to make here.
Neal, I find his being in this mix pretty interesting. You have to figure, he was busted on a drug suspension for PEDs. Now, he comes in at a far lower weight. Maybe they are in fact thinking that this player is not what was advertised on draft day 3 years ago. That is entirely possible, and I had not previously considered that. The opposite could be true, however, that they really like him and that he may be one of the DL locks, with what should be some better speed. But, I have to admit his loss of mass had me a bit troubled, as we were looking to get bigger and faster on D. Maybe he is a lock on the DL, and maybe he is not...
Then again, maybe he becomes one of those players who fits the bigger/faster profile at a completely different position, OLB. There is so much going on with this guy. I hope he can make a great impact on improving this defense, however he is used.
