Anyone that can get inside, with good footwork and hands will trouble Joshua. His inside and spoiling game is actually pretty bad. This patient stalking style he has doesn't cover his weaknesses particularly well, nor enhance his strengths.
Already this has become more of an "AJ LOST" rather than "Ruiz won" Guys, don't get confused.... Ruiz won fair and square yesterday and he is a problem in the division. Ruiz is strong and full deserved the win, it wasn't by luck and Joshua definitely turned up the SAME way he always does. So stop making lists like that till AJ has finished his career, and appreciate that styles make match ups. Ruiz style beat AJ down. Against Fury, Ruiz would have less success.
