Teams have been trying to lure him over for years. According to Stein, the Grizzlies offered him 2 years and roughly $5M in '13. With the cap exploding since then and a similar player of similar age, in Rodriguez, signing for $8M this off season, there's no reason to think he won't command a salary in that range.
I can't see them having any interest in Carter-Williams, Teague will likely re-sign and Holiday, I'm skeptical as to whether they'd offer what it would take to have a chance to sign him given his injury history and the fact that he's good, but not great.
This is similar to Aldridge and Gasol, in that too much adds up to think there's not a good chance of it happening.
