Just a thought that I had, and I'll defer to those who know more about F1 and the 'behind-the-scenes processes' than I do...
Could it be at all possible that Michael Masi had somehow missed that Verstappen was running the newer, soft compound tyres and that Lewis was on 30+ lap old hard tyres?
Obviously to us all watching the Sky Sports/Channel 4 coverage, this was made abundantly clear over and over again, and we saw it unfolding lap-by-lap with our own eyes...but would Masi be watching the same pictures/coverage? What view of the race would he get?
I suppose what I am getting at is that COULD it be possible that Masi DID intend to manipulate the race to put Max behind Lewis but have OVERLOOKED the fact that it would be a non-contest, since Max had a huge tyre advantage?
In that scenario, Masi might have thought 'this will be great for a bit of drama, but Lewis is quicker (had been all race) and should hold-on. Did he realise he was handing the race to Max by positioning him behind Hamilton, and then have an "oh s**t" moment when he realised the true reality of what he had done?
This would also explain, to some extent, the 'it's a motor race' comment...because we all felt that was completely misguided/inflammatory given they weren't racing on an equal footing at that point. Perhaps Masi hadn't understood the discrepancy in tyre degradation/compound
Now, as I said earlier, I am happy to be told this is unlikely/improbable...it's just a theory I have to maybe explain why Masi ended up so blatantly handing Max the race....maybe he had just been following their duel in/out whilst doing his general duties, and thought Lewis would 95% likely hold Max off?
