I mean obviously it wasn’t someone from the staff, but my guess is he gets some of his info from the wrestlers themselves or parents that talk too much.
I believe I saw someone mentioned an interview where Cody Sanderson said “there were no wrestleoffs,” but that could be just semantics in that they didn’t call it a wrestleoff.
Minnow’s posts definitely deserve skepticism and he often doesn’t have the full story, but I do feel like most of the time when he is wrong is when he does the “I’m hearing” thing. He seemed pretty definitive in the comments about the wrestleoffs.
