Caporegime
In two and a half seasons of racing in F1, he's only finished 5 races behind teammates (where both cars finished) but of those 5 races, 2 have been races where a Williams has actually scored a point or two The other way to look at it I suppose is that his team mates have done it when it counted
You could also say that Russell has cost himself points on a few occasions: that crash under the safety car for example. His quali record is utterly stunning: only once has a teammate outqualified him, which was when he switched into a new car - that didn't fit him - mid-season and still landed within a 30th of a second of Bottas.
