Whatever you have to think of McLaren, you have to admit they are always there or there about with the car.
But is thereabouts good enough.....? I dont think so...
Would you rather drive for a team like that or a team that has the DNA like Renault (no where, no where, no where, world champions, no where, no where?)
In the last decade, they have won 2 WDCs...double of what McLaren has won, when the latter has had race winning cars EVERY year. This in itself points to some serious issues in the team. They always emphasize their 'existence to win'...what they mean is to literally win races, but never championships. 2000 was probably their last genuine effort in trying for the WDC, and lost it to Ferrari. Their 2008 WDC was just a bonus.
You point out that Renault won 2 WDCs. But that's literally it. They peaked, then they fell. The end. Many teams do, and that's what Jabber's getting at.
I always comfort myself with the fact that McLaren have outdone Ferrari in the WCC for the past 3 years
Of course, it's not enough, but it's something. Only 1 team can win the WCC at a time. That 1 team happens to fluctuate you know.
