Apparently 'G' as the world now calls him has lost 6kg since the winter so assuming he's kept a lot of the power, should be going up hills a lot better this season.
I'd imagine that the sum of all of Sky's marginal gains ends up being quite useful, how close individually some of these gains are to the edge of rule breaking is up to the doctors/engineers to sort out I guess but as long as they stay on the legal side of it then they'll continue to do well, as long as their chosen riders don't crash early on as in 2014!
I wasn't in at the start but I remember the old days when people who went from zero to IM in 'a number of years' lived in tritalk-land and the idea of taking so long was seen as the long way round. At that point it was seen as being pretty obvious that you could go from zero to IM in 9 months (even though you kinda had to take 12 months on account of races selling out quickly).
Things change and the Pirates are no different it seems
