I bet you that Polain would admit that he doesn't know what FA's he can bring back because he doesn' t know what the draft will be like and what the market value will be for guys like Mathis, Wayne, Garcon and Saturday.
I am sure they have a pecking order but each player has a limit to the price they are willing to pay... See Clint Session, Jake Scott and Charlie Johnson and if you want a star player of the past the Edge.
Do you think the Polains know how much the other teams will offer Mathis, Wayne and Garcon? Of course they don't and thats why they can do all the planning in the world and still have to let one of them walk..
Again I have prove it with the moves the Colts did in the past. They didn't re-sign everyone and their not going to do it this year.
The colts roster is constantly being rebuilt and next year won't be a total rebuild either.
If your at or near the max you can spend and everyone wants a raise then something has to give. You can't pay everyone what they want and someone will have to walk.
