Posey: 3.4 million a year is not too shabby. I don't think Posey can get much more than that from the market. He might want an extension though. If so, something reasonable like 3 years at 3.5 mill per year is reasonable.
House: Only if he's willing to accept his current salary. I would not give more. It's not hard to find good, veterans shooters who wants to win a championship.
PJ: He'll retire with a ring. But if he wants to come back for one more year at the minimum, sure.
Powe: He's a keeper. Let's see what he can do for one more year.
I would not bring back the following, (I would buy out their contracts if needed): Big Baby, Pollard, Sam, Tony Allen, Scalabrine.
Here's a question: Our #30 pick will be guaranteed a contract, right? First round draft choices are guaranteed big money, right? If so, I might consider trading the #30 pick and avoid the extra expense. This is a veteran team, we only want to give decent money to those who can make an immediate impact. We don't need "projects" making big money on a veteran team.
