It's not that he isn't necessarily wrong. It's that he might as well be guessing. The Jays could very well have been in on Aoki and just weren't able to land him. This is a man whose partial job description is "tweet to fans". He knows nothing. If AA sees Wilner in the hallway, he probably whips his phone to his ear pretending a call just came in so he can glide by without having to say hi.
I kind of would have liked Aoki on the team, though... Not really sure where he would have fit, but I think he's a valuable little piece for a team to have.
