Thanks for this, I think it's a very interesting fight and we'll really have no idea until Saturday. It will answer those unanswered questions from the first fight: most namely whether the original was due to a complacent or off-colour AJ who got caught and never recovered, or whether Ruiz is a bogeyman who has AJ's number.
I think too much has been made of Ruiz's power, like it's just a matter of time before he knocks out AJ if the fight goes on. Ruiz has a knockout percentage of around 65% and failed to KO Kevin Johnson just last year who had been KO'd in his previous fight by a Croatian in only his tenth fight - AJ knocked him out in 2. I'm not saying he can't hit, he clearly can, but enough fighters have been able to nullify him and go the distance.
I presume this is what AJ will try to do and will use his natural advantages to try and create a boring fight much like AJ-Parker. I don't think Ruiz will be as cautious as Parker though and knows he can hurt him so will go for it.
