Soldato
Honda have presented zero evidence that they can catch up and overtake the Mercedes and Ferrari power units in the past three years. Ron Denis negotiated a cracking deal with the worst prepared engine manufacturer in F1. I don't know what else McLaren could be expected to do - they've tried the stay loyal and trust approach, which has reduced their performance levels to near the bottom of the field when they're fortunate enough to finish. Or they could try something else and try to be half-competitive at a cost until the engine rules change once again.
McLaren shareholders have very deep pockets. The change to Renault could be a disaster. It would be a disaster if they were slower than both Renault and Red Bull, but that at least is fixable over the course of 1 or 2 seasons. Sticking with Honda has already been a disaster, where they've fallen from being able to contend for a podium or win to an also ran that can sometimes scrap for a point or two, unable to attract sponsors or keep a top driver but being paid for the privilege of keeping the problem.
