Furyk got schooled today IMO. Picks of players with opposite temperaments and skill sets works fine in best ball. To me alternate shot is putting the two people together that are most like each other, at minimum their personality. Even better if their skill sets match. For example ... Tiger/Dechambeau - all about themselves, same distances, not going to talk much. Simpson/Fowler - not long, good short games. DJ/Koepka - bomb it and hope for best. Reid/Spieth - short, great putters, and hot tempered. Then Phil could have played with Finau in the best ball where each can be out of every other hole and it doesn't matter.
