Tonight is the biggest fight show of the year – a fight that has been dismissed by many knowledgeable pundits as farcical but which has nonetheless garnered more viewer interest than any boxing event in a very long time. On the face of it, this is a huge mismatch. Mr Mayweather is unquestionably the finest boxer of his generation and arguably of all time. He is both a master technician and a master tactician in the ring who has made the best boxers of his time look ordinary when matched with him. Mr McGregor is an an outstanding fighter with an amazing penchant for proving doubters wrong. In truth however, this project would be the equivalent of having Mr McGregor compete in an jiu jitsu tournament in a against say, Rafa Mendes – do you really think he would prevail against Mr Mendes under these conditions? My experience of watching very good MMA athletes spar against elite boxers in the gym is always the same – they are quite competitive for the first 3-4 rounds and do surprisingly well. Then around the 5th round the elite boxer begins to figure out the unorthodox or awkward movement and begins to employ ring craft to tire the MMA athlete by making him work harder than he is, making him miss punches etc etc. around the 8th round a very noticeable shift occurs where the elite boxer takes over. I expect a similar pattern tonight- though probably taking less time, given the incredible skill level of Mr Mayweather. Mr McGregors only advantages are youth and size, but punches are not much use if they are thrown at a target that can't be hit, and Mr Mayweather is as always, in fine shape and has never tired in a fight. I would consider it a fine victory for Mr McGregor if he survived 12 rounds and had some competitive rounds among them. Like most , I love to see an underdog take on impossible odds and win, so my heart is with Mr McGregor, but my mind knows this is exceedingly unlikely. In a world of uncertainty I will offer you one certainty that I truly believe – however well Mr Mcgregor does in tonight's boxing match, I ASSURE YOU IT WILL BE MUCH THAN MR MAYWEATHER WOULD DO IN A REAL FIGHT AGAINST MR MCGREGOR.
