Yup.
There's definitely a valid argument to be made for starting the strongest scrimmages, and keeping Mako and Kyle for impact off the bench. Besides, their co parative immobility is not likely to get exposed by the French props!
I prefer the argument that unnecessary changes should be kept to an absolute minimum after a performance like last week - and favour that argument where I would have made different selections decisions anyway. I think we're currently selecting from a position of strength in almost all positions, and the differences are less than the gains to be made with consistency at this point.
After an extra week of training ahead of the Wales match is the time to make any changes for the sake of tinkering, rather than injuries (for the starters at least, bench is always a little more malleable)
