One thing people pointed out is they seem to be better at closing out on three point shooters, and not leaving their feet.
But as far as their defensive efficiency is concerned we haven't seen improvement yet. Maybe we'll get a better idea after playing 12-15 games.
I think the best improvement has been running a real offense. Not give it to Mika and watch him work. Screens, passing, driving much more common this year. Of course that hasn't actually let to a more efficient offense yet either, but we have just had some bad shooting nights. Getting the looks we want, just need to knock them down.
