Ruben Guerrero distinguished his father-son relationship from that of Floyd Mayweather Sr. and his son as the two teams continue marching toward their May 4 clash in Las Vegas.

The elder Guerrero, who was a 2012 finalist for the Boxing Writers Association of America’s Trainer of the Year Award, talked about the cohesion he shares with his son Robert, currently an 11-to-1 underdog.

“Me and Robert, we’re a team, and we’re always together,” Guerrero told BoxingScene.com/CSNBayArea.com.  "I’m there every day training him, and making sure everything’s right…They’re going to see what Robert can do on May 4.”

Ruben and Floyd Sr. have exchanged verbal barbs threatening to fight each other through the media in recent weeks, and Team Guerrero expected the disputing dads to trade blows earlier this month during a commercial shoot for Showtime.  However, Ruben left disappointed.

“He never showed up,” he said of Mayweather Sr.  “He opened his big mouth talking s--t, and I was waiting for him.  I told them, ‘I’m waiting for my opponent.  Where’s he at?’ He wanted to talk s--t to me.  I said, ‘There’s a parking lot out there.  We can do it out there.’ Mayweather Jr. showed up with 10 cars…but his dad didn’t show up.  What’s up with that?”

Guerrero then explained how he perceived the dynamic between Mayweather Jr. and his father, using a well-publicized spat on HBO’s “24/7” series two years ago to prove his point.

“I’ve been with my son for a long time, I know my son like a book, and I know what he can do.  Me and my son love each other, and that’s what makes a difference between them two (Mayweather Sr. and Jr.),” Guerrero said.  “They treat each other like garbage, father and son.  You seen it in the “24/7” when he threw his dad out…When you treat your dad like that, that’s no good.  That’s not right.”

Mayweather Sr. is returning to his son’s corner as chief second for the first time in 13 years after his brother Roger—the man who replaced him—has seen his battle with diabetes exacerbate.  While Floyd Jr. told Showtime's Brian Kenny that he still plans to have his Uncle Roger assisting in the corner on fight night, Guerrero gave his take on the change.

“He’s going to need more than his brother,” Guerrero said of Floyd Sr.  “His son’s going to need three or four guys to help him train against me.  It’s only me.  One guy against two or three coaches he wants to bring in.  It can be four guys.  We’re going to beat him.  I’m going to beat him in the corner because I’m a smarter guy.”
