Sorry, missed this. Yeah scrapping tactics is fun for the viewer but it's stupid for the boxer. Mayweather always did what he had to and look at his record. And that was off the back of a youthful start being an aggressive fighter, but he changed for the better. Look at City when they play these days, we go 1-0 down or it's level near the end we still play the same way, because that's what the best do, execute the gameplan.
Unless there's promoter shenanigans, I doubt boxers will agree to just scrap tactics for a show. It's always going to be more of a heat of the moment thing, adrenaline rush and loss of head thing. Joshua was definitely underprepared for this fight, although how exactly I can't say, I'm not enough of an expert to know.
I don't think Joshua should think about being a wrecking machine. I think that is the mentality that had him lose the fight. He needs to become Klitschko Jr and just use his size, strength, and athleticism and just box his opposition into submission. He should work on his defence and tactics. If you saw him fight Parker, that was the Joshua he needs to think about being (but better nonetheless). With the money Hearn has behind him he really ought to get an elite coach.
The Canelo-Jacobs fight wasn't particularly great. It was interesting and the quality was high but it wasn't a classic in terms of entertainment. It was close but Canelo was the fair winner.
