It is easy to say Lewis has lost the title due to reliablity, but then you could say he won his 2008 title thanks to Massa's engine blowing 3 laps to the end at Hungary.....he has had good fortune and bad that's the way it goes.
I doubt anyone will believe Nico is a better driver than him no matter the outcome of this year.
If Hamilton just had just one engine issue I would agree but hes had what 5 or 6 leading to replacement engines needed. How many has Rosberg or the other 7 Merc powered cars had.... 0.
If Hamilton just had 1 spot of bad luck with his engine its highly likely he a far bit ahead.
