UFC is focused on contender series, thats the guys they are signing to an already huge roster. Doesnt mean they wouldnt bring in an outside champ from Cage Warriors or Legacy but they've been signing 3-4 fighters a week the last 7 weeks and will also do that in Nov.
If I'm them I'd try for Usman but he might be still with PFL and just allowed to fight in Titan while they are shut down. Dont know what the story with him. Then you have some of the Cage Warriors guys, I think Cartwright probably gets signed if he wins this weekend and Hughes and Garry are the two big prospects coming up but they need more seasoning before UFC. Then you also have Paddy, he's a big name and draw out there and is solid but I dont think he's elite or ever will be but he's def someone who should be making the jump to UFC or Bellator soon.
