You are aware that merely losing their UFC debut does not make them "regional-level fighters." And some of them are replacements on short notice. Also, "regional level fighters" is vague, as MMA talent varies by region. Additionally, they are not filling the cards.
The fact that I can name more great signings from just this year than you can from your list of "regional level fighters" should indicate that I am not in the wrong here.
So to completely end this pointless argument. I'm going to list all of the great and good signings or debuts that UFC made this year. I won't include this year's DWCS roasters or signings like Bo, Ikram, or Marshall. Because that would simply be too long.
Michal Figlak(just got signed) Jailton Almeida,Rinat Fakhretdinov, Joanderson Brito, Aliaskhab Khizriev, Daniel Argueta,Gadzhi Omargadzhiev,Javid Bashara, Michael Morales,Hayisaer Maheshate,Manuel Torres,Chidi Njokuani, Thomas Almeida, Daniel Zellhuber, Azamat Murzakanov,Victor Henry, Caio Borralho, Jack Della Maddalena, Taylor Lapilus, Tatusoro Taira, Muhammad Mokaev.
There are probably more but I don't have time for this. And this is just this year.
