Legendary trainer Freddie Roach told ESPN on Friday there’s still “a shot” that Floyd Mayweather will agree to scrap Manny Pacquiao.

Finances and drug testing protocols have long been roadblocks to cementing an absurdly lucrative bout between the 36-year-old Mayweather (45-0, 26 KOs) and 34-year-old Pacquiao (54-5-2, 38 KOs).

"Every big fight that was supposed to happen in boxing happens somewhere along the way, I just hope this one isn't going to happen too late when they're both washed up and not the same," said Roach, 53, who has been voted Trainer of the Year on four occasions by the BWAA.

"I still have hope. Mayweather's in the same position [Pacquiao] is. You've only got eight fighters in the world that can sell on pay-per-view and make money. That's why I give it a shot."

Pacquiao (54-5-2, 38 KOs) will face Brandon “Bam Bam” Rios on November 23 at the CotaiArena in Macau.

Reportedly manhandling sparring opponents, the 27-year-old Rios (31-1-1, 23 KOs) 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.

Accordingly, expect Pacquiao to knock an inferior Brandon Rios onto Queer Street within 11 rounds roughly two weeks from this evening.

Meanwhile, as the reigning pound-for-pound king, Mayweather is tentatively slated to battle an unnamed opponent on May 3.

A defensive virtuoso defying Father Time with an incredible work ethic, Mayweather seems destined to equal Rocky Marciano’s 49-0 mark and retire as an unbeaten titleholder.

However, as Roach aptly noted, "every big fight that was supposed to happen in boxing happens somewhere along the way.”

Although extremely unlikely, perhaps Floyd Mayweather’s “big fight” is “going to happen” in the future against Manny Pacquiao.
