Rios (31-1-1, 23 KOs) is set to battle the 34-year-old Pacquiao (54-5-2, 38 KOs) on November 23 at the CotaiArena in Macau.
“It’s my time,” said Rios, 27, a former WBA lightweight champion who employs controversial strength and conditioning coach Angel Hernandez.
Rios most recently suffered a unanimous decision loss to Mike Alvarado in their March rematch.
Conversely, Pacquiao was violently knocked onto Queer Street by Juan Manuel Marquez last December.
Granted, Pacquiao has been defeated in consecutive matches by the 40-year-old Marquez (55-6-1, 40 KOs) and Timothy Bradley.
However, in actuality, Pacquiao outclassed the 30-year-old Bradley (30-0-0-1, 12 KOs) and was battering Marquez before the juicehead landed a savage overhand right that finished the scrap at 2:59 of the sixth round.
Reportedly manhandling sparring opponents, Rios is a ferocious brawler looking to aggressively throw fists.
Unfortunately for the native Texan, Rios is also sloppy and substandard defensively.
With elite footwork and the uncanny ability to deliver punches from all angles, Pacquiao will absolutely feast on Rios’ chaotic style.
