I have little doubt some of those type of quotes have been made, and unfortunately comments/attitudes like that continue to disparage the game of 8 man, and it's annoying to have come from 8 man coaches. I will also add that the weaker teams in 8 man have happened to be been in your backyard in SW MO the last few years, so that certainly hasn't helped it look any different from your perspective, since i'm guessing you're down there somewhere. So, I understand what you're saying.
Ironically, we're somewhat making the same point about 8 man needing more depth, albeit in different, at times heated ways. As of now, there is a large disparity between the top level 8 man teams and the lower tier. While I think the same could be said about classes 1-6 as well at this point, people pay more attention to our lower tier because our overall number of teams is so much lower (23 in 2018) and teams that switch end up picking up the lower tier teams on the schedule out of necessity, which can make 8 man seem easier than it is at times..... The only solution is for more teams at the 8 man level. That is going to require one of two things happening: Either MSHSAA is going to have to take the bottom 28, 32, 48, etc. enrollment teams and assign them to 8 man like Iowa does; or the perception of 8 man is going to have to switch from being viewed as a last resort to being viewed as a wise, viable option. Unfortunately, I don't see either of these happening in the foreseeable future.
