Here's the best site I've found for this.

Graham is set to earn 12 million next year between his salary and roster bonus, but only counts 3.7 million against the cap if they release him. I could see Gute offering him 4 or 5 million to keep him around. He's not worth 12 million, but he might be worth keeping around for an extra 1 million relative to what he'll cost to cut.
