We usually play man for the first couple minutes.
The reason we don't play man is to protect Luka from being put in ball screens.
He really struggles to help on screens and he picks up fouls. So its a two fold problem.
I don't understand why Fran doesn't switch to man with the second unit with Luka on the bench.
I've been saying the same thing (mostly to myself or my wife if she'll listen to me). The first unit needs to start in zone and the second unit should play man. It doesn't make any sense personnel-wise to do it the way Fran has been.
