MMA's Benson Henderson Picks Winner of Masvidal vs Diaz, I Already Beat Em Both!

Benson Henderson is the ONLY pro MMA fighter with wins over both Nate Diaz and Jorge Masvidal ... so, naturally, we asked him for his prediction on the 1st ever 'BMF' main event!

First off, Benson LOVES the whole "Bad Mother F*cker" belt concept -- praising the UFC for a "great marketing ploy." He also has a lot of respect for both fighters.

Benson famously defended the UFC lightweight title against Nate back in 2012 -- and won that 5-round fight via unanimous decision.

Then in 2015, Henderson took on Mavidal at "UFC Fight Night" in South Korea and won that fight via split decision.

So, who wins when Diaz takes on Masvidal at UFC 244 Saturday night at Madison Square Garden???

Benson says there's one guy who clearly has the edge if they fight a traditional MMA fight.

But, if these guys REALLY want to prove who's the baddest MOFO around -- and they stand toe-to-toe and slug it out for 5 rounds -- Benson says that changes everything!

Henderson ultimately makes his official prediction. Watch the clip, it's great stuff.

As for Benson's fighting career, the 35-year-old is coming off 4 straight wins in Bellator -- and is scheduled to take on Michael Chandler in Japan on Dec. 28.
