I agree that Posey is the only must keep FA. I'm also hoping that since he is just "over the hill", the C's can use extra years, even let him retire with the extra dough if he wants, and start his extension at his current salary. For example:
3.5 - 3.8 - 4.1 - 4.4 - 4.7 over 5 years.
And then the MLE and LLE could be used to lure guys like:
Swingman - Ross or Evans (let TA walk, he's not worth 2.75 mil, if you can get one of these guys for less).
Big - Mourning, Diop, Mutombo, Brown (resign), Turiaf, maybe even Kwame Brown (if he came mega cheap for a Perkins like role)
Point - Duhon, Dooling, Arroyo, Anthony Johnson, House (resign)
