I don't think Button ever had a rookie as a teammate...Was Button ever pushed by a rookie or unknown driver as hard as Adrian was pushed by Di Resta?
Adrian had the better strategies in the last few races whe the car was at its best, which hurt Paul and cost him potential points and bundles of time too. Adrain is a very good driver but Paul and Nico have much more to learn and are far less experienced so are the best pairing for them going forward.
Maybe Sutil did have better strategies sometimes, but that's because he qualified higher. And you neglect to mention that Di Resta's best result of the season, 6th in Singapore, was achieved with a far superior stategy than his teammate's and lucky timing with the safety car.
