I'm sorry if I sounded like I was saying that there are only a few good mecanum teams. If you look at my post, you'll see that I used the word "Personally", meaning that those are some of the teams I've seen UP CLOSE that use mecanum wheels effectively. I've never seen your team compete, therefore I can't pass judgement.

The "nonadrive" is an evolution and you are correct, they discarded the center wheel in 2011. One of their mentors told me their drivers were rarely using the center wheel so they removed it. Earlier versions (from previous years) used mecanum wheels instead of omni wheels. They didn't see a huge benefit and wanted to reserve more power so they switched away from mecanum.
No need to apologize but mentors should be positive (in my humble opinion) and an engineering judgement in such matters is not particularly relevant ;o). Facts are facts, there are records and plenty of video out there. If a student wants to build a hover-craft for rebound rumble, we tell them it is a crazy idea. If a student wants to build a mecanum drive, we tell them it requires special skill sets - that is all I'm saying. A student, to be taken seriously, should endeavor to offer informed opinions in a public forum.
Good luck this year!!
