Rizin needs to put at least 6-8 shows every year, like in PRIDE days, to develop their fighters and find new stars. Grand Prix every year september - december + 3, 4 more shows from january - august.
There is a good market potential, plenty of viewers in Japan, Korea, China and the time is also acceptable for Europe on sunday morning-noon.
They have acces to large talent base from around the world through all those reigonal organisations, they just need to pick the best like they started with Jiri, Teodoras, Nemkov, + legends like Cro Cop, Wanderlei, Fedor to increase popularity, pick other good avaliable fighters in the world and crossovers from kcikboxing or other combat sports like Aliakbari.
They need to secure enough revenue and icome to offer more money to those fighters than their regional organizations offer them, and to represent another step forward in their career, an attractive opportunity. Rizin would also need to share some money to other organizations for their cooperation.
And of course they need enough shows to establih themselves and their fighters. A show every 1.5 -2 months would be optimal to keep good concentration of talent and stacked cards, like in the PRIDE days.
In that way RIZIN would be able to close the gap towards UFC step by step, and to develop their own quality fighters that would be ranked inside top 10 and significant in the world.
