A year ago, WWE lured Ronda Rousey from UFC to the squared circle.
Stephanie McMahon hopes to pull off that feat again with a pair of recently retired megastars.
The WWE chief brand officer told TMZ Sports she would "love" to have Rob Gronkowski and Conor McGregor join the promotion.
"Anybody who has a real big personality. I'd love to have Gronk in the ring. Conor McGregor, huge personality," McMahon said. "It's really about bringing in the biggest personalities with the best athletic ability."
McMahon neither confirmed nor denied having conversations with representatives for Gronkowski or McGregor about a potential WWE debut.
