I'd love to see Porte in yellow because Sky wanted to lose it/saw no need to keep G in it, while also seeing Porte as a safe holder. And then struggling to get him out of it.
Surely they'd rather avoid 2 and a half weeks of the pains of defending the maillot. Not to mention press conferences, doping control etc. Not saying they want Porte to have it, but it will be a burden at this early stage. Regardless, he's a bit far back on G and Froome.
