I agree that it will be impossible for us to keep our current roster intact next year without crippling our cap for years to come. I have been beating this drum for a while now.
The big names that will require a huge salary cap hit are Newman and Ware. Ware will be the sacred cow of the two. They will find a way to keep Ware regardless of what it costs to resign him, but the cost will probably be exhorbitant.
Newman "needs" to be resigned, but he is going to cost an exhorbitant sum as well. I am not sure we can keep both. That is why the Pac Man signing, while risky, makes some sense.
The players that I can see us losing this year or next year could be as follows:
1. Roy Williams (safety) unless he plays well (to his old form) and extends his contract in a cap friendly manner.
2. Ken Hamlin. He is basically rented for one year.
3. Henry. He is getting long in the tooth and he is good, but not great. He can be replaced in the draft in the draft.
4. Spears. Solid, but unspectacular.
5. Marion Barber. He is a fan favorite. He might even be a top 10 back. I doubt that he will be worth what his cap hit is to resign him. Let's get this straight. He is WORTH the money, but NOT WORTH the salary cap hit.
6. Columbo. He will be worth more than we will be willing to pay.
Keep in mind that when you lose a free agent (Like Barber) there will probably be a compensatory pick given to partially compensate the team for his loss. A player like Barber would probably net a 3rd rounder as compensation, at least. Loss of compensatory picks for letting a free agent go is just one of the opportunity costs for resigning Barber.
