The UFC will be alright......yeah most casuals that only watch for GSP and Silva might no longer watch since they're done but more stars will emerge.
The irony is that both guys was supposed to have that super fight a few years ago that would've been the biggest in MMA history and they're both done.
Weidman got the cacs behind him, so he'll get a boost of popularity. Ronda still there. JBJ has taken Silva's spot as the top dawg, but has to finish his opponents more excitingly. You also got cats like McGregor thats gonna become a huge star at FW, but he's hurt. There's still alot of exciting fighters in the company, but its gonna take time for them to get at the same level of popularity GSP and Silva were at.
I'll still watch.....I'm not gonna quit watching otherwise, though its a sad day for MMA.
