More political correctness run amok.
It would appear that the PTB (Powers That Be) (or, more likely, Mr. Moxey all on his own initiative) feared a backlash if they included a photo having anything whatsoever to do with GUNZ!, so he "lost" the photo ... and also conveniently omitted all mention of the team or their championship.
And now doesn't have the integrity to own up to what he did, so he tries to blame it on the photographer. That might explain the lack of a photo, but my HS yearbook has a couple or few entries that are text only, with no accompanying photo. It can be done.
So in attempting to avoid a possible backlash, he generated a for real, honest-to-goodness BACKLASH.
