Ray's clutch shooting and spreading the floor is better. But Lee's over all offense, gets out and runs, cuts, drives is better.
I think Lee will make the offense run smooth, like it did when AB was in the line up. He can cut, and spot up, and will run with Rondo which would be nice to have only one or two players trailing instead of the 3 or some times 4.
Rondo
Lee
Green
Wilcox
KG
At some point we may see that line up on the floor at the same time, good on D and will run the crap out of most other teams.
