Anyone that thinks prime Bruno would beat prime AJ should be ignored. Can't believe I'm having to respond to this nonsense, I suspect it's someone being subjective and bias againt AJ (probably due to politics) more than any actual thought, but here we go.
Bruno got beat up pretty much every time he fought a top 10 boxer, AJ has beaten multiple top 10 boxers. Comparing AJ, a two times champion, holding 3 titles which he collected from 3 individual champions, with 7 title defences, with an olympic gold medal, a win against a true legend of the sport, 8 wins against top ten opponents, 88% KO ratio and won a title in just his 16th pro fight, challenged for a title 4 times and won the title 4 times....compared to Bruno, KO'd 5 times, whose career win was against the limited and lucky to be champ Oliver McColl, never made a defence, lost 4 out of 5 title fights, it took him 44 fights and a whole lot of luck (Tyson's prison sentence, McColl's lucky punch vs Lewis) to actually win the title.
The biggest comparison is that at that 16th fight mark, AJ had beaten a legend in Klitschko and beat Chaz Martin for the title....Bruno at that same point beat a guy called Barry Funches who had more defeats than wins and had only fought one non-domestic boxer.
Bruno never beat a boxer who was coming to fight him unbeaten, in fact his opponents were picked to fight him because they had been largely proven to be KO-able. The only two unbeaten boxers he fought were Lewis and Tyson and both KO'd Bruno. AJ has beaten 6 people that were undefeated, that's every fourth fight he beats someone up who has never lost.
Their careers are chalk and cheese. Bruno was an excellent domestic champion but always too slow, clumsy and chinny once he stepped up to the world stage. He never proved he should be at that level and took a few absolute beatings. AJ has proven himself without any contention to be in the top 3, some would rightly claim top, he has beaten everyone he has faced and has put everyone on the floor everyone except Parker.
Honestly, anyone that thinks that Bruno would beat AJ needs to have a serious look at themselves in the mirror and ask where they went wrong with their life....and I say all this as someone that got a lot of joy out of watching Bruno's career.
