If your big man is an unstoppable offense threat then you can do whatever you want, even a defensive shot blocker is fine to park in the paint. What you can’t have is big men that don’t have effective post moves that get taken off the dribble in defense because they’re too slow.
The Kansas big man got exposed on defense which would have been fine if they couldn’t stop him on offense but he was just a put back dunker more or less. I can see our bigs getting exposed against the right opponent, it’s up to Cal to change the lineup quickly and abandon them if it occurs.
If UK gets exposed with its bigs chasing shooters around the perimeter, I agree. Go with PJ, Johnson as your 5/4 and three guards.
Cal loves slopping it up in March/April with games in the 60s, but he's preached the Gospel of "You've got to be able to score" and "you can't let your opponent take you out of your game" lately. If he means it, go small and dictate tempo. Don't play into the opponents' scheme by slowing the game down and turning it into a grind it out. Speed the game up, maximize possessions, and let your skill advantage dictate the final outcome.
