Why so? They're playing their own ball?
How has Snedeker's ballstriking been so far? On paper at least Kuchar is better there, though seems a bit cold so far. Great / hot putting is not what you need in fourball. It seems to me you want to maximize makeable birdie looks without risking par too much - and that comes from good ballstriking.
Interesting...I like those for the most part but I don't like Phil and Kuchar playing this afternoon. I don't quite understand how DL3 could bench Snedeker in favor of those guys.
Lack of distance and grititness/killer instinct/whatever you want to call it for Kuchar IMO. He's a great guy to log top 10s week in and week out on tour, don't think he's got a great RC game.
