An overtime loss in Allen Fieldhouse with a freshman laden team with multiple players in serious foul trouble is "getting our azz handed to us?" Seems a loss makes it difficult for you to maintain perspective.
People also calling for a zone based on Self's use of one need to understand the difference between those two situations. Self switched to a zone to attack our weakness. You're wanting Cal to switch to a zone to address a deficiency. A switch is more likely to pay dividends in Self's situation, but it was also a high risk strategy. Had even one of our front court players stepped up, you'd have seen the triangle and two go away quickly.
If a team's issue is related to effort or understanding assignments, switching to a zone does nothing to address those two issues. You'll simply switch from playing bad man to man defense to playing bad zone defense.
