WBA have three in a load of divisions. (a Super/ regular & interim) The Super champ is also some times known as the unified champ o4r the undisputed champ atsch
I would say so yep. They force people to fight mandatories or vacate so it's a good way for people without American TV network backing or huge promoters to get a shot. Although it can lead to some big mismatches, because if you are with a huge promoter you are only given 25% to fight the champ, so if you have other options and the champ isn't a big draw (but a good fighter) you'd probably turn it down. A case in point would be Kell Brook, with Golden Boy/ Haymon/ Top Rank having practically all the top names at Welter, he wisely took the IBF route to become champ. However since he's been champ Leonard Bundu, Amir Khan, Tim Bradley, Shawn Porter, Sadam Ali and Devon Alexander all turned down final eliminators so he's had to fight Jo Jo Dan and the next mando will be between Fredrick Lawson and Kevin Bizier.
