UFC 306 on Saturday provides plenty of intrigue, and for once, that does not entirely have to do with the proceedings inside the cage. The Ultimate Fighting Championship finally plans to get out of the box with its production by running the Sphere in Las Vegas, and it looks to be an ambitious one-off project due to the work needed to pull it off and the excessive costs that have made headlines ahead of the show. That alone provides reason to tune in, but the top few fights sell themselves to an extent, particularly the main event.
