If Ferrari has a competitive car - and the team don't discriminate against KR to support SV - then clearly he has a chance
A very small one unless he can get on terms with Vettel in races. He's shown little sign of being able to do that thus far.
Most of those suggesting Kimi might be able to come to terms with Vettel in races are pointing to the tyres as the main reason. I agree the odds are in favour of Vettel winning their intra-team battle, but I also believe that the main reason Kimi has been unable to keep up during races has been tyre wear and their thermal operating window. With the reports of tyre wear having much less of an impact this year and them being significantly less thermally sensitive, there's reason to believe he might have a stronger showing. Not guaranteed by any means, but there is some logic behind the thought process
Yet people seem to rate his performances in 2012/13 with feeble tyres?
I think he drove well, but it was more the fact that the car was so gentle on its tyres than Kimi being a tyre wizard. I said so at the time and pointed out that when it was cold, or raining, Kimi really struggled to get heat into them, which was the main reason why his qualifying was so poor at wet races. His best results were when it was hottest.
Lotus seemed to have one strategy - to try to do one less stop than everyone else. But I wasn't convinced at the time that was the best and I'm still not 100% now. The main issue was the thermal operating window and the Lotus being gentle on it's tyres allowed Kimi to exploit that only when the conditions were right. When they weren't, he struggled.
If the new tyres lead less management, there's no reason to believe he won't be better. After all, if he can match Seb for one lap pace why not race pace? I can't think of much beyond the tyres (but I appreciate I can't guarantee I'm right, either!). I think Kimi's been pretty poor overall at managing the Pirelli tyres but occasional flashes have shown us he still possesses decent raw pace. The Michelins didn't require management and he did fine with them. Not saying these will be the same but if they are more forgiving than they have been in the last few years there's some logic in believing that this may play to his strengths. Or, alternatively, not highlight his weaknesses so much, whichever you prefer
