I think Bellator invested aggressigely in Eastern European talent like Moldavsky, Amosov, Magomedov, Nemkov, Shabily, Tokov etc who were all to be quite honest....No brainers for the UFC to sign but they typically don't like investing in high level prospects internationally because they have markets that value them so theyd have to pay more, where they can farm US talent for pennies on the dollar thats better for their major demographics anyways. This of course is nothing new for Bellator we saw the past generations of Minakov, Saranavskiy, Khasublaev, Vasilevsky, Shahbulat, Blagoi etc But it does seem they're getting them younger and more polished prospects now which is awesome.
They also heavily invested in the US wrestling prospects very young into their MMA careers like Caldwell, Fortune, Joey Davis, Storley, Honeycutt, Aaron Pico etc. Over the last few years which I think is similar to the Eastern Block strategy, long term a great plan for growing talent.
Right now as talent rises and or is acquired in Bellator, there really is little good tests for them until they reach the top 5 of the division and even then its quite...mediocre sometimes.
Heavyweight Ryan Bader? Irrelevant.
Light Heavyweight Nemkov? Top 10 level LHW talent, I think the LHW is shallow in the UFC and Nemkov could potentially be a threat to the title. Young, strong, fairly athletic and well rounded.
Middleweight Mousasi? Well I think Moose is still a top 10 MW. Do I think he can beat Izzy? Not now, maybe the Mousasi who fought Kyotaro or something but hes about 80 professional fights into his career and in his late 30s now. Mousasi has always been one of the most skilled fighters in MMA who could never really put it together when it counted most. He wasn't impressive vs Shlemenko or Lavato either.
Welterweight Amosov? Strong, young, undefeated. I think he is a top 10 guy probably but currently may be overrated. We all know Lima can bang but he really hasn't shown us since the Askren loss if he can handle a wrestler and his cardio when guys wear on him is exceptionally bad. How good is Amosov vs how badly was Limas weaknesses exploited? He didnt look amazing vs Storley who I see as nothing more than another Wrestler trying to make it in MMA.
Lightweight Patricio? He isn't someone who would be able to keep his head above water at 155lbs for long vs talented prospects and top guys, the size is too much. He did catch chandler though.
Featherweight Antonio McKee probably the most exciting dude outside the UFC right now. Not sure after Patricio and Caldwell being dispatched in 1 round each whos next for him at Bellator though. The division isn't exactly exciting. Id love to see him vs many UFC guys though.
Bantamweight, theres no champ but none of their guys stand out to me anyways.
