Great question. On one of the comments on Youtube I see the reply "Kippy Freeman". Boxrec lists a Patrick Freeman at heavyweight around this time. Google has a picture of Patrick admittedly much slimmer, fighting Gary Bell (another Holyfield sparring partner). Thoughts? https://www.gettyimages.com.au/deta...rade-blows-during-a-bout-at-news-photo/222761
If Freeman is the guy who was sparring Holyfield, his record (4-5-2) is not as good as his skills. He was obviously a fighter with no financial backing. He fought 11 times, 6 opponents were undefeated, his opponents had a combined record of 53-8-2. He fought two "prospects" back to back in Bell and Po'uha. If he had the financial backing to pick opponents and the time to prepare, his record would have looked a lot different. From the video with EH, he looks to be the kind of "B" side opponent who could pull an upset over a paying opponent.
His record ain't much with 4 wins and 5 losses. On the plus side, he has 3 KOs out of his 4 wins. So that's an over 90 percent KO rate
