It's less about the analytics team for one side being better than the other, and more about the home analytics team having more control over course setup. The same Euro analytics team that won last year 16.5-11.5 lost 19-9 in America two years before. The last time we had a Ryder Cup where the home team didn't win by 5 or more points was 2012, and even that one was shaping up to be a blowout until a miracle Sunday singles.
When these data guys can identify marginal advantages and then get control of the course, it makes it really hard for the home team. You add in a situation like we had last time where most of the team got sick the week of the tournament, and it gets ugly quick. It's time to take course control away from the home team.
