3. Teofimo Lopez Sr.
Lopez Sr. won a lot of praise when his son defeated the legendary Vasily Lomachenko. However, he suffered a shock defeat to George Kambosos in 2021. Kambosos knocked Lopez down early and dominated the fight. But Lopez Sr. refused to accept the result.

He showed a lack of class as he said that everybody knew that his son won the fight. This was delusional and disrespectful. It also didn’t help his son because he made Lopez Jr. appear arrogant in defeat. Coaches should protect their athletes and instill humility (via SBNation).
