I can only conclude that you are applying some sort of logical fallacy whereby you conclude that if Red Bull are very unlikely to win using the balanced team approach, they become more likely to do so with an unbalanced selection.
If we say that they have a 5% chance of victory by a traditional team selection, do you accept the logical possibility that a different strategy might have a lower, say 2%, possibility?
And if you believe that there is a selection that would give a significantly higher possibility, do you think that you are being reasonable by claiming that you know what that is, and that it is as simplistic as you suggest, and yet it is something that you cannot point to any example of any professional team manager ever having tried? (and did you not know that GT teams comprised 9 riders for many decades?)
If we take a figure of 5% as Red Bull's chances of winning with the sort of balanced team that most here are advocating, what probability of victory would you suggest your proposed line up might offer?
