I just think, at the end of the day, Ruiz probably wants to be as awkward as possible and you can't fault him. He obviously thinks AJ's biggest weakness is his brain and wants to unsettle him anyway he can.
AJ strikes me as a guy that's fairly smart in life but pretty thick in boxing, basically the opposite of Fury. He's well spoken, thoughtful, but in the ring he absolutely needs to have a plan. It all went out the window with Ruiz, short notice killed their prep, killed the gamelan, made him think on his feet against an unknown enemy which he's crap at.
Ruiz won't be an unknown quantity this time so he's got to rock the boat any way he can. No chance he'd ever agree to come to Wembley or Cardiff without a massive fuss.
