He got rocked and stunned 3 or 4 times in his fight against Volkan. Yeah, he did KO volkan but He was very hittable and vulnerable in that fight. Rakic would butcher his legs with 4 or 5 leg kicks, then KO him with a high kick.
He would also get destroyed by Jan, one good left hook counter from blachowicz would put him out cold.
I said that before but people think Rakic duck Jiri.
