It's nice that Russell has copped a ride that his potential dictates he should have. If he were smart, he'd play the role of good team mate to let Hamilton have the best chance at his 8th title - assuming he doesn't win it this season. What goes around comes around, especially in racing.
Once Hamilton has No. 8 in the bag, I wouldn't be surprised to see him retire while still whole and healthy. And the F1 world then becomes Russell's oyster, with a compliant team mate signed to help him begin his push for titles.
Yep, play good teammate, I'd almost go as far as try to get Hamilton to take on the mentor role (Hamilton seems to be inclined to be nice to the younger drivers), learn from him.
Hamilton has 2 years left tops, I thinks it's just locking the 100+ wins/100+ poles/8 championships done, a completely unbreakable record then he walks away.
