1) One example doesn't prove anything.
2) If you pay attention to bombastic absolute statements like "X kills Y," you've already lost.
3) A very reasonable argument can be made that practicing one thing and not another makes you better at the one thing, and diminishes your skills at the other. There's a pretty good reason why we don't just jump into M2M when our zone isn't working.
4) Opposing recruiters would be stupid not to use our defense against us. If you're a football coach, trying to sign a drop-back QB, and your competitor runs a Wing-T, you'd be a moron not to tell the kid that your system will prepare him for the NFL better than the relic system.
5) Why do people really need to make excuses for zone? And really, if you were a kid with no connections to SU and just starting to watch college basketball and were about to become a fan, do you really think you'd choose a zone team? Is your identity really tied up in the Zone?
