2. Brock Lesnar UFC 200
Brock Lesnar is possibly the most marketable fighter the UFC has ever had, and his win at UFC 200 would have meant the company could put him in at least 1 more high profile fight. A high profile fight means big money for everyone involved.
It appeared that Lesnar had guaranteed another pay day for himself and the UFC by beating Hunt, only for everything to come crashing down when 1 of the 8 drug tests he took leading into the event came back positive.
Now everything is up in the air until more is known.
