The UFC uses Las Vegas as a home base for a lot of their main events, and with the appearance of The Sphere becoming a premier event in the sport world, many leagues will eventually put on events there.
However, when Dana White was asked about what he thought of the NHL Draft, he didn't hold back and gave a brutal answer, and even stated the UFC will do a way better job at hosting a sporting event at the Sphere.
It doesn't make much sense for Dana White to call out the NHL or Gary Bettman, but the Draft seemed to be received well by most that were there in person and by the people who watched at home, and without out a doubt the league should be proud for what they accomplished last weekend.
