It is true that Matt doesn't believe the zone is as good a defense as man. Another problem with "last year" was that if you were only going to play two of the three (Vince, Biggie, Haas) at the same time, the only zone would leave Haas out when playing it. If you were playing Haas and wanted to play a zone, then you play all three OR really go small down low. The depth up front and desire offensively for only two bigs was a huge detriment to a zone with Haas. Athletes help in man and zone, but the rebounding is improved in a zone with athletes as well as the coverage when your area is flooding with more offensive players than you have defense in that area...the athletes do allow "better" coverage. Still, the main reason was Matt doesn't believe the zone is the best defense and then a distance 2nd is what zone would you play and still have Haas playing other than a 2-3 and either you are small down low or your offense is hindered as many believed two bigs played better than three...
