As the son of Irish boxing legend Barry McGuigan, Shane initially ventured into the sport as an aspiring amateur bidding to follow in the footsteps of his famous father - and he definitely had some talent. Despite sweeping up national titles in Ireland and earning selection for the 2010 Commonwealth Games, it quickly became apparent that he lacked the passion and willpower to remain dedicated from a physical standpoint.
His transition into coaching was more by chance than forethought. It came when Barry, manager to European super-bantamweight champion Carl Frampton at the time, asked him to hold the pads for his Northern Irish charge. In the end, Frampton's long-time coaches Gerry Storey and Gerry Storey Jr took themselves out of the equation when the pair struck up a formidable bond.
A 24-year-old McGuigan was then tasked with leading Frampton's corner for the most important night of his career to date; a world-title shot against Spain's Kiko Martinez. And it was a test they passed with flying colours, getting their hands on the IBF championship via unanimous decision after a commanding display over 12 rounds.
'I was doing the majority of the work with my dad, and on fight day Gerry Storey and Gerry Storey Jr were coming in to do the corner. They'd be the main voices because dad was managing Carl,' McGuigan recalls.
'But eventually I became the head voice because Carl was listening to me and tuned into me the most, so they [Storey and Storey Jr] didn't want to be part of the Kiko Martinez title fight. They didn't feel like they had done the work and if he lost then it would be a reflection on them, so they said they weren't going to be part of the prep and that was fine.
'Carl just looked across at me and said "let's go on our own then". And he won it, put on an amazing performance and that was when I was 24.'
Frampton went on to create history under McGuigan's tutelage before they went their separate ways in 2017, first toppling bitter rival Scott Quigg to unify the super-bantamweight division and then becoming a two-weight world champion by moving up and beating 126lbs chief Leo Santa Cruz.
They came unstuck against an improved Santa Cruz the second time around, nonetheless, and amid a legal dispute with Barry and his Cyclone Promotions company, Frampton parted company with Shane after his first professional defeat.
Yet, McGuigan's remarkable work leading his corner at such a tender age had not gone unnoticed, and as their working relationship began to sour another two marquee names came through the door.
The first of those was David Haye, the former heavyweight and cruiserweight world champion turned A-list celebrity on a comeback trail after almost four years out of the ring, and the second was George Groves, Carl Froch's iconic Wembley dance partner still hunting a world title after three unsuccessful attempts.
Whispers of McGuigan's wisdom beyond his years had clearly done the rounds and both Haye and Groves, two ex-pupils of esteemed British coach Adam Booth, were impressed enough to instil their faith in him.
He went on to spend two-and-a-half years with Groves, inspiring the confidence-shattered super-middleweight to seven straight victories, his holy-grail world title and bragging rights over Chris Eubank Jr before a career-ending stoppage at the hands of Callum Smith came in 2018.
Though in the case of Haye, who was in his late 30s when teaming up with the 28-year-old, there would not be a similar fairytale story. Evidently beyond the peak of his powers, Haye initially claimed knockout wins in straightforward return bouts against outranked journeymen Mark de Mori and Arnold Gjergjaj, which preceded a disastrous night against Tony Bellew.
After rupturing his Achilles tendon in an astonishing sixth round, the crestfallen pre-fight favourite hobbled on valiantly for the next five with the effective use of only one leg, before McGuigan finally put him out of his misery by throwing the towel in the 11th. The waving of the white flag marked the end of their working relationship as well as the fight, and when reflecting on his time with Haye, McGuigan concedes that the gulf in age made for too awkward of a dynamic.
'There was eight years between us,' he says. 'He's born in 1980 and I'm '88. He'd also made millions and millions of pounds, was a two-weight world champion, couldn't walk down the street without getting recognised.
'That was hard because even though I came from a famous dad and boxing heritage, I didn't box as a pro, I never won world titles, and he gave me the respect because he listened, but I was still developing as a coach and finding my feet.
'I could get through to all the people that gave me attention and discipline, but I think David knew his body really well and I was sort of figuring it out. So it wasn't the best relationship, but if I had it do all over again I wouldn't say no to it. It's just frustrating because I wish I'd have got him at the right time.
'It's the same with George. We had an eight-fight run together and he won seven of them, won a world title, it was great, but I wish we'd have got together sooner.'
McGuigan insists he would not rebuff the opportunity to coach Haye if he could turn back the clock. However, does the more rounded and experienced 34-year-old spot mistakes when glancing back at his younger self?
'There aren't regrets, but there are a lot of things that we could have done better, and if I could do it all again I would have done certain things differently with certain fighters,' he admits.
'But I still don't have many losses to my name, and the losses that we have got are the likes of Callum Smith against Groves, Vasyl Lomachenko and Ryan Garcia against Campbell.
'They're all elite fighters. It's not like we're losing at domestic level.'
Haye and Groves arrived in McGuigan's gym at the tail end of their careers, with the fundamentals already deep-rooted in their respective skill sets after numerous years in the sport.
Contrastingly, the likes of Caroline Dubois, Scotney and the Azim brothers are raw prospects in need of schooling and nurturing. This gives McGuigan the chance to mould them into exactly the kind of fighter he wishes, which he admits is more rewarding as a coach.
'I prefer it, but from an investment standpoint it's not an immediate return,' he points out.
'If you've got X amount of hours in a day, it would be easy for me to say I'm just going to take on championship fighters, because they always gravitate towards you anyway if you're a good coach. So I'll get the Hayes, I'll get the Groves, Campbells that come in.
'Even Lawrence Okolie started elsewhere, Fowler started elsewhere. Those are the ones that end up coming to you anyway.
'But if you get them young, it's 10,000 hours to ingrain a habit, and if you ingrain those habits and you're doing 100,000 hours, 200,000 hours with the perfect technique, they're going to be a better fighter.'
Taking unseasoned youngsters under his wing prevents McGuigan from having the same kind of regrets he has with Haye, Groves and Campbell. Should they remain under his tutelage for a lengthy period of time, he can eventually end their working relationship knowing they journeyed as far as it was possible to go. There are no what ifs.
And while not every boxing hopeful he joins forces with will be completely fresh, McGuigan expects his door to continue revolving after slowly shaking off his new-kid-on-the-block tag and acquiring a reputation as one of the most esteemed trainers in world boxing.
'There's so many kids coming out of the Olympics now and I know that I'll get a few of them in a couple of years' time,' he asserts. 'I might not get them now, but like with Lawrence, I know I'll get them soon.
'Luckily Lawrence hadn't failed, he just had bad performances and knew he was capable of more, so he came in. And that's down to the individual to say, "I'm better than this, I need to go to a gym and have the respect".
'That's not even me blowing my own trumpet, it's just I can get through to them because I have a level of respect within the industry that goes a long way. You can have the best coach in the world, but if you feel like you're the main attention and it's their first rodeo, then that respect gets lost and they don't listen.
'That's the good position I'm now in and it's taken years to develop, to gather that respect from my peers, in the coaching industry and also from fighters.'
