Two years ago the American team travelled to Scotland in the knowledge that they would not be fielding their strongest possible line-up.
The US have ensured they don't suffer a similar fate this time by introducing what is unofficially known as the "Horschel rule".
And come next Monday it could be Europe feeling as though they are travelling to an away Ryder Cup without their strongest line-up.
This is because Paul Casey has been the continent's most consistent recent force and Russell Knox is also in strong Stateside form. Both are playing to a standard that would make them big assets to skipper Darren Clarke's team.
But neither player is in the continental line-up even though they, along with Rory McIlroy, are the only Europeans competing in the PGA Tour finale.
