well it would kind of matter. if we were to start Curry, for example, it'd be around the same if we start Bonner/Blair/Diaw defensively since it wouldn't mean much defensively. the thing that'd open up the floor would be Duncan's mid range, giving Curry more room to work on the inside.
it wouldn't matter if Pop is dead set on starting Diaw because Curry/Splitter would never work on the offensive end and the Lakers bigs would force both to shoot outside shots and easily rebound over them since they can't shoot so you'd be forced to stick with Bonner to open up the floor some for Splitter. Curry's deal has never been defense or help defense, so i'd shutter to think Pop starting Tiago to then play Curry/Diaw or Diaw/Bonner.
