I like Livingston and would definitely sign him. The problem becomes, what kind of money? Unless he's coming on for the minimum, I don't like it, because I want to make sure that Posey is back in green. Sure, Livingston has more upside than Posey, but Posey fills a bigger need right now as he can backup 2-3 positions well. Livingston on the other hand would really only help as a backup 1, which is probably a bad idea for his career as he'd get minimal minutes backing up Rondo. And I don't like the idea of Rondo and Livingston on the court together, as neither is a great shooter.
So while it's a nice idea, given our salary position and the relatively small time frame we have to win a title, I don't like Livingston at anything more than the minimum. And it seems unlikely he comes for that.
