Brundle is a complete moron, the only people doing the number of laps on a set of tires that would have allowed Hamilton to two stop were going painfully, painfully slowly. Brundle decided that damaged front wing meant 3 stop instead of 2 stop.... nonsense. THe Merc in multiple races has gotten stuck behind the Williams in normal conditions(new tyre, old tyre, undamaged car, high/low temps), fact is Hamilton was going to struggle to pass Bottas in a drag race. he could be massively faster in the sections with more corners but the passing down the straight was impossible.
Hamilton was destined for third from the second Massa went out... that is where he ended up. They were hoping going longer in the first stint would help the next sets of tires both with life span and speed on lower fuel but it simply was never going to work at the pace he was going. Button has exactly zero effect on his race.
