Oscar vs Trinidad for me stands out like a sore thumb. He ran for the last 3-4 rounds and he cost himself the W. Even then, I feel he still won the fight. But no question taking the foot off the gas cost him dearly. Which other fights can you say a fighter cost himself by displaying poor tactics. Loma vs Teo where he didn't fight for the first 5 rounds. He took way too long to start to execute his game plan ( a dumb one at that ) Ben Tackie stole this one after being down on the score cards. Garcia should have stayed away from exchanging but I must admit I haven't seen it in a while. I believed he opted to trade when he should have got on his bike after being miles in front in the 10th round? This content is protected Garcia stole defeat from the jaws of victory?
Loma vs Teo Teo vs Kambosos Lara vs Canelo Gary Russel Jr vs Loma Zhang vs Parker Canelo vs Bivol All of them are rencent examples of fights where a stupid strategy was a major part of a fighter's defeat. My memory is trash. This question in the classic forum would be a really insteresting question.
Hagler vs Leonard. He puts himself down in the hole by losing a lot of early rounds not fighting southpaw.
