Does the fact that Russell has managed to come 2nd in qualifying, only 0.03 seconds behind Bottas, detract from Hamilton's performances over the last season or more? I'm not a big F1 fan and will occasionally watch the first few laps, or a bit more if it looks like there might be some rain, but the fact that some 22 year old (yes I know he's a professional driver) can step into your car and comfortably beat 18 of the other 19 drivers out there seems to suggest that it's the car that is the main factor rather than the organic bit behind the wheel.
Like you not a massive fan but for me its a little from column A and a little from column B. Mercedes are without doubt leaps ahead of the other teams so the car must give him a massive advantage but also with so little opportunity bar testing, he's clearly shown he has an abundance of talent to come in and take the car to second. The car may be good but you have to get it round and quickly.
