Rondo's layup will be used with the "have the LS going to north/south and pull the shot stick on the opposite direction" move.
You cannot be going directly to the rim though, so if you start at the left elbow and drive straight down towards the block and pull back on the shot stick you should get his ball fake/spin lay up.
Not sure on Crawford's though, used him a lot on the Knicks in 2K9 but his sig layup always seemed random when I pulled it off.
