I'm probably in the minority, but I like Lee for Memphis. They need the spacing offensively, and I think he fits their defensive system very well. He was probably a bit of a disappointment in Boston, but he will fit in very well for Memphis.
I'd also like to point out how underrated (or overrated, depending on how you look at it) the MLE is. Every offseason you hear "give so and so the MLE" and now all kinds of people are saying "what is Memphis doing, he's on such a bad deal." That may be true, but he "only" signed for the MLE when he signed that contract. MLE is more significant then people realize.
