Reed and Spieth had the magic in 2016; Bubba? What goes well with a dickhead? Maybe Bryson? Maybe pray for someone to volunteer? Finicky is not someone I'd want to play with.
Reed and Spieth have been great in both of the last two Ryder Cups. Part of the reason Tom Watson got stabbed like Julius Ceaser is he sat Spieth and Reed in Gleneagles for no discernible reason in an afternoon session right after they'd just destroyed Poulter and Gallacher. Keegan and Mickelson got destroyed in their place, which is Example A of why Tom Watson was a garbage captain.
I'd say the US pairings will most likely be:
Spieth/Reed
Thomas/Fowler
Koepka/DJ
Webb/Bubba
My prediction on the four captains picks would be...
Woods (obviously)
Mickelson (almost certainly a lock unless he somehow withdrew himself from consideration, which he won't do)
Kuchar (don't love it, but you need someone to pair with Tiger or Phil and he can pair with either)
Kisner (I'd rather take Finau; I think Tiger would rather take Bryson; I think Furyk will ultimately pick Kisner)
I think Bryson might be a great RC player, in part because he'd infuriate the Euros, but he seems lost in the sauce a bit these days, and needed a better summer to grab what seemed like a lock earlier this season. Part of the reason I don't like taking Kuchar and Phil is you need to build for the future. This is why it was so dumb to take Ryan Moore last time around instead of Justin Thomas. It was equally stupid when JB Holmes and Bill Haas got picked for the President's Cup over Koepka.
As for the Euros, Bjorn actually has a really difficult decision to make with Sergio, who has been absolutely garbage of late. (He's missed 8 cuts in his last 9 starts, and seems to be in full IDGAF mode now that he has a major.) If Bjorn takes Sergio over Thomas Pieters, who was a monster at the RC last time around, he's playing with fire. If Sergio plays like ****, it could get real ugly in Paris.
I think I'd still take him, ultimately. He's one of the best Euro RCers of all time. Maybe he feels revived. This event always seems to do that for him.
So his picks would likely be:
Sergio
Stenson
Casey
Knox
