Then go be a fan of Syracuse where you won't be disappointed in not seeing a zone.
Most of the problems have been more so with the backside help being late in rotation than it has been with Haas being a poor defender on the wing. You are over-reacting to a very small sample size and then potentially forcing our strength in defense in to a weakness. This season in the B1G, for example, the zone you are clamoring about would have been dreadful. Most teams in the B1G would have simply shot over this zone as the weakness of a zone is allowing perimeter shots. Syracuse makes up for the glaring weakness in a zone by recruiting long and athletic players but then also alters their offensive approach geared towards those players as well. The reason for this is because Boeheim has always done that and has coached that way for nearly four decades at Syracuse.
If you were a fan at Syracuse and because they have struggled this season, would you be clamoring for Boeheim to be playing a man to man? No, because that isn't what Boeheim is skilled at coaching...so why clamor and beg for CMP to suddenly start coaching something he isn't good at doing?
