By Gav Duthie: Mayweather and Golden Boy promotions have decided not to opt for chief undercard support this Saturday like they did with Amir Khan v Collazo but the undercard is shaping up nicely. There are some fairly competitive fights and titles on the line. Here we rate the fights and speculate if any might outshine the main event.
Humberto Soto 64-8-2 (35) v John Molina 27-4 (22)
Fight Rating: 9/10
Fight Type: All action
This has the potential to be the fight of the night. I love fighters like John Molina. Will he ever become a world champion, probably not but it doesn’t matter. He always entertains and always gives us good fights. He’s a Mickey Ward, Arturo Gatti type throwback who will keep you on the edge of your seat until the final bell. He might feel a little hard done by on Saturday as he watches Mickey Bey fight for a world title after he amazingly stopped him in round 10 for his only loss to date.

By Robert “Big Moe” Elmore: I re-watched Erislandy Lara’s fight with Alfredo Angulo and then re watched then his fight with Saul Alvarez. The one big difference that I saw in the Angulo fight was; he let his hands go. He stuck to his usual stick and move style, but he was punching when he saw the openings. There was no hesitation on Lara’s end and Angulo’s face showed the results. Even when he was knocked down twice he continued the same level of activity he started out with. Where was this Lara against Canelo? Where? Angulo, like Canelo, is best when he sits down on his punches. 
By Robbie Bannatyne: They say in boxing you are only as good as your last fight. On the evidence of Saul “Canelo” Alvarez’s last bout, a boxing lesson by the magical Floyd Mayweather Jnr many experts predicted the death of the career of Saul Alvarez- who had barely turned 23 years old at the time of the bout.
By Bradley Dee: From bell one last Saturday night in his fight against former WBA/WBC junior middleweight champion Saul “Canelo” Alvarez (43-1-1, 31 KO’s) in Las Vegas, Nevada, it was apparent to me that Alfredo Angulo (22-4, 18 KO’s) is a shot fighter and has nothing left. The two wars with Erislandy Lara and James Kirkland have finished Angulo, and I see no reason why he shouldn’t retire immediately, or risk brain injuries.
By Robert “Big Moe” Elmore: I wrote an article titled “Fighters; it’s okay to have defense. No Really it is” a little while ago. It touched on the Alfredo Angulo and Erislandy Lara fight along with other topics. In the fight with Lara, Angulo defense was terrible. The swollen eye and damaged faced spoke volumes about Angulo’s defense and it spoke very loud and clear last night against Saul “Canelo” Alvarez. 
By Jay McIntyre: “Gameness” is a term used by people that train dogs in the highly controversial sport of dog fighting. It describes a dog’s ability to “make the scratch” (come out of their corner to fight), without flinching or showing cowardice. These dogs do not have to be the largest, nor do they have to inflict the most damage. In fact the winner in many cases simply needs to be one that is unwilling to quit and will continue to make the scratch.
