Paffet will never race a McLaren, unless one of the 2 incumbants gets hurt. He's a solid tester, and i think he'd be a half decent mid pack racer, but not McLaren driver quality. Di Resta and Hulk and even Sutil will be the pick of Merc backed drivers, for the Merc works team or maybe McLaren. I see Force India as a junior team to both at the moment
