Were RBR too conservative? Seb just did a 1:16.5s. I thought the Mercs had better tire deg/pace but. Anyway great result for them, aided by the SC of course.
You can't do 1:16s for a 40 lap stint. Fine to kill the tyres on the penultimate lap, not much sense in killing the tyres with 35 laps to go.
If Red Bull had the tyre life to pressure the Mercs, they would have been pressuring them. But because you can't pass at Monaco, the only option was to shadow the Mercs and hope for a bit of good fortune - it was clear from the first laps that Merc were aiming for the one-stopper, and the only luck that came Red Bulls way was the safety car which put Hamilton in a compromised position (which he exacerbated by going too slow).
