I wouldn’t call Rosberg weak!
The equality adds to Lewis legacy for me. He has had highest quality of teammates especially when compared to Max and Michael.
Alonso, Jenson, Nico and George who else on the grid has had anything close to that level of teammate.
Of course I would love Gasly, Albon and Checo which top driver wouldn’t
Alonso has had Lewis, Kimi, Jenson and, for a few races, Jacques. In terms of non-WDCs who have won GPs, he has had Jarno, Giancarlo, Felipe and, of course, Esteban.
