JACK BRABHAM 31
No. 1 driver for rear-engine Coopers, he must finish at least third and take fastest lap to win world title. Can rely on tactical team aid from his Cooper colleagues.
STIRLING MOSS 25�
Driving private-entry Cooper, he may have to win race plus fastest lap to top Brabham, but could finish second and still stand high man in the final point standings.
TONY BROOKS 23
In a Ferrari, he has outside chance for world championship, but to gain it he must win at Sebring while Brabham fails to add points and Moss adds no more than five.
