Good valid points Mark & they also reminded me that your description also applys to Abel Sanchez in the Canelo 2 fight... sorry to digress
I just watched a vid of Sanchez talking about Ruiz being more pumped for AJ than he was for his bout with Parker, but Sanchez was in the corner giving Ruiz advise v Parker and he wasn`t countering the jab like he did v AJ, Ruiz has said Sanchez wasn`t even in the gym with him while he prepared for Parker, he had to train himself.
I get it,the only cornerman that could have helped AJ was Jesus or someone with those kind of qulifications.
