With the introduction of the 30-second shot clock and a host of additional rule changes, scoring increased rather dramatically in 2015-16. What's good for the scoreboard, however, is bad for the defenses.
Then again not every defense collapsed last season. Coaches like Kansas' Bill Self and Virginia's Tony Bennett still know a thing or two about preventing points. Good or even great defense will still be there for the taking this season if you know where to look.
