And they cannot seem to even get that. So thew problem is his age in my opinion.
I don't think any GM wants to be the guy that gives a 38 year old a lot of $$$$ and the have it blow up in their face.
Well then their only other 3 options are waiting to the deadline to deal him (hoping a team gets desperate and doesn't mind losing the compensation picks if he leaves them in FA), sign him, or let him walk after next season and receive compensation picks for him.
Out of those 3 options the best possible move would most likely be to re-sign him.
