One tactic Europe has used in the past (particularly Jacklin) was to pair same nationality players and generate mini teams within teams. When ever this has been tried, the Europeans had a winning record by nationality except for Irish pairings!!! (mind you, I never profiled for those for north and south!). Spanish pairings have a fantastic record.
With Stenson and Garcia likely starters, I do wonder if they might look at Blixt and Jiminez with a preference for the former
Mollinari has a very good Gleneagles record, albeit I think that's been on the Kings Course?
The Centenary course is the longest inland course in Scotland and that might be a factor yet . Colsearts would be interesting as a mercurial type in a fourball, or perhaps paired with Donald in a foursome
McGinlay needs to be a little bit sensitive to giving McDowell a reputational pick I reckon, and especially if he brings Padraig into the fold as another assistant alongside Des Smyth as is being mooted. This could turn into an Irish love in if they aren't careful, albeit if Darren Clarke has aspirations to captain at Hazeltine you'd have thought he'd be on the management team somewhere too
I'm not totally convinced that McDowell is playing unless he can force his way into the team on merit.
I think the one they must dread slightly is some journeyman doing a Van de Velde at the Open and suddenly gatecrashing the party
Europe's developing an interesting balance though of streaky mercurial players and steady fairway hitters.
McIlroy, Dubisson & Garcia are capable of hitting hot streaks (as would be Poulter if selected) then you've got mechnical sorts like Stenson, Kaymer, Rose and Donald to balance them
