I dont think breaking was his problem, the HAAS in front did an excellent job with DRS to keep him at bay, it was only when KMag got out of DRS with Sch that Lewis took him.
It would have been the same either way round.
Lewis was hampered by the collision at the start and never really fully recovered.
If it had been the main race, then yeah maybe Lewis would have taken more risk.
Mick has a place in F1 , with a half decent car, he is showing that he can do it, I dont think he is not going to win any WC's but I think he may well win races.
