We need to get a few bodies at DT and OT, and take care of most our guys.
Canty, Boley, Rolle and Baas are examples. Generally speaking he picks up one higher priced FA per season. Our cap being what it is though, will probably mitigate what we do this year (much like it did last off-season).
The cap hit involved is workout bonus (depending when you cut them) and signing bonus (including restructured payments). I believe in the past you had to pay the outstanding signing bonus the year you cut the player (the "guaranteed" money) but under the new CBA, it can continue to be spread out over the original life of the contract. Since both of their contracts are up next year anyway, the cap hit in 2013 isn't too bad (about 1.4 for Boley and 3 for Webster).
