Game changers .... the last 60 years

Babe Ruth
Peyton Manning
David Fairclough
Lester Piggott
Lev Yashin

If by game changers you mean people who literally changed their respective games, then probably none of the above.

Martin Pipe
Shane Warne
Johan Cruyff

Kilkenny

Lance Armstrong ?

The All blacks ?

Dick Fosbury. Maybe Graeme Obree.

My three favourite sports are horse racing, rugby and cricket in that order.

Lester Piggott
Sean Fitzpatrick
Shane Warne

fosbury .... g s
Nicklaus ?

Did the Op intend this to be a a greatest athlete of all time thread. This is not my impression. Kindly clarify

Cliff Richard
Tennis has never been the same since he sang at Wimbers.

Hard to say without some kind of definition.

Dick Fosbury would have to be in any list I'd guess. May not seem like such a big deal now but at the time and for many years afterwards Bob Beamon's frontal still of the long jump in the 1968 olympics was, maybe alongside Ali's wide eyed lunging post Liston, one of the iconic sporting images of the 20th century. The Black Power Salute (of 1968 again). Bannister collapsing over the line in 1954. Jesse Owens interspersed with pictures of Hitler. The Italian chap in the 1908 marathon up and down like a fiddlers elbow and then eventually carried over the line and disqualified. The Iron woman in Hawaii who having swum two and a half miles, cycled 112 miles and ran a marathon collapsed about 50 metres from the line and was passed and then proceeded to crawl her way to and over the winning line. That ball from Warne to Gatting and Gatting's reaction. That spell from Holding to Close where every ball seemed millimetres away from taking his head off. Bustino versus Grundy. Dancing Brave in The Arc. Crisp. Red Rum's third national. Coe after he retained his 1500 metres crown after being written off by the British press. The dirtiest race in history (Seoul 1988). Buster Douglas not just beating but battering Tyson. Nicklaus and Watson at Turnbury was it? Tiger Woods smashing up the Masters field at 20. Buck Shelford having his testicle pulled off by a French forward and playing on.

Not all game changers but all indelible images.

Martin Pipe.

graham taylor ?

basically went route 1 with Watford, Wimbledon copied it and a decade later passing back to the keeper was banned

Yes. Martin Pipe.

performers rather than administrators like that numpty swiss egit in charge of fifa... eh ?

Rugby changed a great deal for the better but due not to a player but to the move from a shamateur, winter game to a professional, summer game. So that doesn't count.

Jack Wa*ker showed the way to win the PL title. $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$

Arsene Wenger changed players' attitude towards themselves.  He had them looking after themselves like never before in terms of diet and training.

Undoubtedly Jimmy Hill and his cohorts in abolishing the retain and transfer system and the maximum wage.

Wenger certainly a game changer for the English game.

Someone'll put me right here, but didn't F1 alter the points scoring and introduced various new laws in order to stop Schumacher when he  was so dominant?
