If I was him I would play defense like my coach taught me.
Full court trapping press.
REAL Kentucky basketball.
You got a deep team and can't really play defense so if it was me I would make them play full court pressure.
I believe that might be the only way that you can wake up the defense in this team is by forcing them to full court trap.
The theory is they're going to score on your half court defense anyway so why not play the full court pressure game and if they score off of that well fine they were going to score anyway
... But you can also manufacture some steals manufacture some energy manufacture pressure by picking up and putting full court trap in.
You don't really have anything to lose and you have 14 damn players.
