Considering he no longer works there, Ben Askren is still generating a ton of publicity for Bellator MMA.
It helps that his former employer, Bjorn Rebney, has continued to be vocal about the future of "Funky" -- who recently signed with ONE FC and got into a shouting match against longtime mixed martial arts (MMA) veteran Phil Baroni -- if for no other reason than it allows him to take potshots at UFC President Dana White:
Rebney talks to Sherdog's Beatdown Radio:
"It didn't follow the philosophy that the UFC espouses. It didn't follow their tagline, and it was too bad that they didn't even make him an offer. I understand if they'd made him an offer and Ben turned it down, but to not even make the No. 6-ranked guy in the world an offer, then stop saying the best fighters in the world fight in the UFC ... The reality with Ben Askren is that the UFC didn't want a one-dimensional Bellator champion being champion of the UFC, so they shied away from him, and then they've gone radio silent on him, trying not to engage in conversation because they don't want the conversation to continue. Ben Askren would have run the table at  at the UFC. Ben Askren ran the table here; he would have run the table there."
It would have been interesting to see Askren in a post-Georges St. Pierre UFC.
We won't get that chance, however, as "Rush" put himself out to pasture and "Funky" was flat-out rejected by UFC. In fact, White went so far as to tell the former Olympian to take his "stupidness" and fight in Pluto (White didn't know ONE FC was still in business).
So, do the best fighters in the world all compete for UFC?
Depends on who you ask.
