I agree about the many mistakes that Mclaren is making. They have slipped badly. I don't see any efforts to correct the problem either. I think 2018 will not be a good year for them, lots of DNFs, blaming Renault, etc
Although Ron's influence on the company was extreme, his absence seems to one of the factors that's involved in this. There is no one in charge who wants to make the difficult decisions and clean up the operation.
