So... both guys keep a respectful distance trying to land stuff from the outside.
When Jiri commits to a charge he throws some dangerous shit that forces Poatan to back up. The problem is when Jiri comes forward inch by inch instead of full on charge, or just stops and stands in front of Poatan he gets kicked in the leg. He has to stay outside or get all the way inside. In the middle Poatan chews the leg up. When he stumbles Jiri with it he tries to see if he can sneak that left hand in there.
Jiri feinting for the takedown is good as it keeps Poatan guessing about whats coming.
As time goes by Jiri gets more confident to get close and Poatan is backing up more and more...thats when he decides to shoot for a single, and eventually gets it. Jiri had a great oppurtunity to finish here. Yes Poatan was defending well but Jiri should have committed to an all out assault. He also was a bit passive in letting Poatan to return to his feet.
He didnt seem to want to clinch with Poatan though. He backed out as soon as it ended up there, but then charges right back at him. He doesnt seem to want to clinch though. Jiri keeps on bullrushing Poatan backing him to the fence and the round ends.
Second rd, Poatan starts letting his hands go more. Trying to take control of the octagon, trying to take back the center and not get backed up. Jiri using crazy feints to get it back. It works and he has Poatan backing up again. Leaping push kick pushes Poatan into the cage. Jiri busier with the kicks is helping to keep Poatan against the fence. Poatan trying to regain the center again. Starts throwing kicks back. Not just leg kicks but to the body. Both guys seem to have success with their kicks. Poatan throws and Jiri counters (situations like this could be good for Jiri in this next fight) Jiri lands a big right and backs poatan into the cage where Jiri rushes him, Jiri teeing off. Not all of them are landing 100 but he is all over Poatan.
They clinch up and he tries to throw an elbow but Poatan disengages. Jiri tries to lure poatan to the center with "come on" gesture...but Poatan uses the distance to start firing off kicks when Jiri doesnt engage. Jiri starts switching stances, cos he felt those kicks. Poatan hits him as Jiri clinches. Poatan defending well to not let Jiri do some spinny shit. Jiri throws him off. Poatan immediatley takes the center. They trade hard leg kicks. Jiri lands a hard right on Poatan who backs up and really Jiri just got too over confident here. He needed to be throwing combinations and not just throwing one shot here or there. His punches were landing but Poatan was OK and landed a counter left which put him down.
So my advice would be
1) throw more combinations
2) commit to an all out assault if it goes to the ground
3) Get better at dealing damage in the clinch
4) When in close, this is the death zone, you cant ponder and throw a punch and another punch, you have to string them together to commit to total violence. He gave Poatan too many openings thinking he was more hurt than he was. Poatan is better at dealing with this chaos than others.
5) More takedown attempts would be good. He seemed to abandon the idea when Poatan got up.
