Regardless of what Joe Rogan said, just because he said it doesn't add credibility that it did or did not happen, arguments like this are like a child repeating something back to you in a silly voice and expecting it to discredit what you are saying, fucking asinine.
If you watch the tape there is plenty of evidence to support Kos not being out of it yet, which is why you typically look for a few more unanswered shots before calling it.
Brock Lesnar took far more shots against Carwin and came back to finish the fight.
You wana say the stoppage was justified, fine, there is a good amount discrepancy to support that, but don't try and act like its dumb to think it couldn't have been a poor stoppage, that is just plain stupid.
Edit - For the record, I celebrate at ever Kos loss, I dislike him as a fighter and as his persona.
First of all let me say, I respect your dislike for Koscheck. Secondly it is dumb to think it was a poor stoppage. His head was being bounced like a basketball by huge shots, he was in a submissive fetal position, he wasnt reacting to the punches, and his eyes were directed towards herb deans feet. He was done plain and simple. The fact is, it was an excellent stoppage, Dean got in there quickly and saved him from taking any more massive shots which were definitely coming. The only reason i can imagine that people would be saying it was a poor stoppage is because they are parroting rogan.
