You know what the problem is sometimes, people don't watch fights to actually see how good fighters and their level. People see statistics and accomplishments and assume a fighter is elite based on that. Like in this case with Ikram saying he's a 4 time Combat Sambo champ. That's great and all, but how he develops his mma game at a high level is what matter. And he hasn't come close to doing that yet. Izzy who's good great TDD and would pretty much go right through Ikram like nothing. Perreira would knock him out as well.
If people bothered to watch Ikrams fights it would be pretty clear rather than just listing his sambo numbers and that he put up a decent fight for 3 mins vs Khamzat before getting KO'd.
I was checking his fights once he was being talked about and a name came up, Nahson Burrel. It sounded familiar, I looked it up and yes...he was a UFC fighter for 2 fights and I recalled he fought Wonderboy. So I watched the fight. Now Burrell is pretty much a career journeymen who's had no success in bigger promotions like UFC and Bellator. He doesnt have a background in anything and is a low level grappler. And with all the hype around Ikram, I was surprised that he only beat Burrell 29-28. Keep in mind this fights was a year ago. He used his wrestling and got TD's but Burrell got up or reversed him every time and by the third round he was landing his strikes while Ikram couldn't apply his grappling well.
To answer your question, Park is actually a more proven and better fighter at this point. So that is how you can compare them. Before we start talking about Ikram vs the champs, let see him beating some unranked guys first. But if he looks like he did vs Burrell, he's not gonna have much success.
