As Europe and the United States go through the motions, the ceremonies and the practice rounds that precede the serious business at Whistling Straits, spare a thought for those Ryder Cup heroes that might have been.

This will be officially the 2020 Ryder Cup, but the pandemic impact has not been merely to delay the showpiece by 12 months. The teams have taken a hefty shake-up too, since last season was so unexpectedly interrupted.

There are players that looked destined to play a big part on the Straits Course last year that will instead be far from Wisconsin, their hopes of starring having been scotched by the postponement.

Qualifying criteria were necessarily changed, to ensure it will be in-form players who line up for each team, and both the US and European teams would likely have looked radically different in September 2020.

Here is a look at some of the winners and losers of the team-picking puzzle from each side of the Atlantic.

EUROPE

Winners: Englishman Paul Casey had made a sketchy start to his bid to qualify for the team, with little to shout about before the COVID-19 crisis struck. He had time to make up ground, certainly, but Casey needed results quickly. He has since had them in abundance, with a tied-second finish at the US PGA Championship last year a reminder to Padraig Harrington that he wanted in on the action. Ten top-10 performances in 2021 catapulted the 44-year-old to automatic selection and a fifth appearance on the team.

Norway's Viktor Hovland was not in the conversation 18 months ago, when the tours ground to a mid-season halt, although a win at the Puerto Rico Open in February 2020 saw him leap from 100th to number 60 on the world rankings. The Oklahoma State University alum's form since golf resumed has been nothing short of spectacular, with 24-year-old Hovland climbing to a career-high ranking of 10th in August. Since the turn of the year, he has had seven top-five finishes, including a win at the BMW International Open, and his hot form could mean the heavy metal fan cranks up the dial for Europe.

Losers: Danny Willett and Victor Perez were firmly in the picture when the tours halted in March 2020, but neither will be making an appearance. Englishman Willett, the former Masters champion, has slumped from inside the world's top 40 golfers to outside the leading 150 on the rankings after a wretched run of results that meant he stood no hope of a wildcard.

Perez's form dipped at an inopportune moment, after he previously stayed firmly in the mix. Across his last five tournaments, Perez has endured five missed cuts – at The Memorial and all four of the majors – and no top-10 finishes, meaning the Frenchman could also not realistically be thought of as deserving of a call from Harrington.

Perez wrote on Twitter: "I am, of course, disappointed to not be selected to the team. However, this is an opportunity for me to evaluate, become stronger and apply new lessons to all parts of my career, and for that I am grateful."

UNITED STATES

Winners : The US were planning on picking four wildcards but switched that to six amid the COVID-19 uncertainty, meaning the automatic selections also shrank from eight to six, and their line-up for Whistling Straits looks markedly different to how it surely would have turned out a year ago.

On the fringes of the world's top 50 and emerging as a bright talent, in March 2020 Collin Morikawa still needed to get a move on to come into captain Steve Stricker's thinking. The 24-year-old is now a two-time major winner, ranked the number three best golfer on the planet, and he led the final US points list, reflecting his dramatic surge. Bryson DeChambeau would likely have found the results to make the team, given he was coming into form after a rocky spell; now he is a U.S. Open champion and has the big personality to take the Ryder Cup by storm. Patrick Cantlay also eventually qualified by right, winning the Tour Championship and consequently the $15million FedEx Cup, earning a debut.

Losers : All-time great Tiger Woods was still in the picture when global sport called a hiatus, yet the last time the 15-time major winner was seen in public he was struggling by on crutches after the February car crash that police said he was lucky to survive. Three-time Ryder Cup man Patrick Reed – 'Captain America' – was in the frame for an automatic pick, too, along with Gary Woodland and Webb Simpson, until the world changed.

Eighteen months down the line and those four have been usurped, with Stricker taking the players ranked seven to 10 on the points list (Xander Schauffele, Tony Finau, Jordan Spieth, Harris English) as wildcard picks but deciding against choosing 11th-placed Reed or 13th-placed Simpson. He also selected the players in 12th and 14th (Daniel Berger and Scottie Scheffler).

Reed, having been troubled by pneumonia and an ankle injury lately, took his omission "like a true champion", Stricker said. Six rookies feature for the US, Stricker looking to the future but backing his team to succeed in the present.
