I'm not a GM and don't want to be one, so I have no idea of how you get there, I'm just talking broad based strategy. We are rebuilding. No need for the old vets unless they are willing to be mentors for cap friendly salaries. You'll need some vets to play those roles, but at the right price. If it's not possible and cutting guys like this would basically have the same outcome as keeping them, then I guess we have to hold'em (thanks Mickey).
Ideally, NOW is the time to start building the foundation to a future championship calibre team. Any player you can not picture as being part of that future is expendable. Get the old guys out of the way (physically and financially). I couldn't be more thankful to guys like Cam, Taysom, etc. But they will not be cornerstones in our future. It's hard to say goodbye to these kind of guys, but as the line goes in an old Cowboy Mouth song, "I might love you, yeah, but I love me more." We should focus on doing whats right for the franchise in the long term. As I said in a previous thread, don't chase, build a future.
