Uuuhhh.....Defense?

I just played an entire playoff series in an online association, and both me and my opponent shot almost 60% for the series....on Superstar difficulty!!!  I knew the defensive AI was bad, but is it getting worse?  It's nearly impossible to force players into bad shots because they still hit almost everything!!!  Seems like the only way to play defense is to get steals, but nothing else seems to work.
