At a time when Anthony Joshua is vying to become the new face of the heavyweight division, David Haye is embarking on his own Cinderella story and Amir Khan and Kell Brook are flirting with the idea of sparking a rivalry that defines a generation, the fuse on British boxing's current boom was actually lit on November 23rd 2013.

Carl Froch changed the game after his first encounter with George Groves. The Nottingham fighter started his climb towards to success at a time when terrestrial television was still scared to invest in boxing after Audley Harrison put viewers to sleep instead of his opponents. He earned the respect and love of the sweet science's hardcore fans behind the Sky Sports paywall – winning four world titles with a crowd-pleasing attitude of 'work hard, punch harder' – but it was this domestic rivalry with an unfancied 25-year-old from Hammersmith that finally captured the imagination of elusive casual fans.

For six rounds in Manchester on November 23rd, rank outsider Groves channeled his inner Rocky Balboa, flooring Froch within three minutes and schooling the WBA and IBF super-middleweight champion. That didn't last and Froch taught the watching world all about his warrior spirit, winning the fight and retaining his titles via a controversial ninth round stoppage. When referee Howard Foster decided Groves could take no further punishment, he was winning the fight ahead of Froch on the cards of all three judges.

Knowing the British public loves an underdog story, Matchroom promoter and British boxing supremo Eddie Hearn chased a rematch and Froch vs Groves II was set for Wembley Stadium on May 31st 2014. The rivalry and dislike between the two men was very real and in front of 80,000 fans, the rematch became the biggest fight Britain had seen in the post-war era. For the first time since Lennox Lewis held the world heavyweight title, British boxing had a global buzz and it all started on that mild summer's night.

18 months since knocking out Groves with the Punch of the Year and hanging up his gloves for the final time, Carl Froch caught up with Complex to talk about British boxing's new dawn, the Anthony Joshua hype train and the science of a superfight.
