Anyone that thought Punk could actually fight doesn't understand how fighting actually works. They literally bought in a guy off the regional in Mike Jackson just so Punk could maybe have a competitive fight and he got clowned on. Punk has zero athleticism. He could have trained for 20 years and he would still get his ass kicked by anyone remotely athletic.
He's the polar opposite of guys like Francis Ngannou or Cyril Gane who could either make up for incredible deficiencies through sheer explosiveness or pick stuff up incredibly quickly. Punk is uncoordinated and moves like an 80 year old man. I legitimately thing the otehr guys could have stood there and let Punk throw hands and he wouldn't have been able to knock them out.
