Matias looked sharp against Jukembayev, but showed he can be tagged, and I think Regis is a level above and would take the Rougarou in this, but a great fight, with guaranteed fireworks.
I love Matias. I'm a sucker for him mostly because i made a shitload of cash betting on him against Jukembayev and Hawkins. But Prograis is stylistically a bad matchup for him. Saying that...Matias is a bad matchup for EVERYONE out there. So he definitely has a solid chance. But i would favor Prograis and think he likely wins by TKO in the mid/late rounds. Prograis is so sharp with his punches and has good footwork. He can deal with the pressure i think.
He's absolutely relentless and a nightmare to fight but Rougarou hits like a truck and I think his power will prove decisive in that one against the easy to hit albeit beastly Matias. That dude who beat Matias hurt him badly and almost had him out of there at one point IIRC
Matias being puerto rican you never know he might have week knees and a weak heart so far he hasnt shown any signs of it but you never know cause like the Notorious BIG used to say "Its like the more ricans we have the more quiting we see."
2 glass chins with brutal knockout power, sounds like an exciting fight. i see matias getting the upset.
