My theory (based on feck-all) is that Sky are trying to present this as a procedural or administrative issue rather than a full-bore doping case - "it's paperwork and nothing more". It kinda worked for Wiggo so lets go with it again. The press and public's attention span is limited, so slowing things down effectively dilutes the story.Quite what is taking all this time isn't clear. Are Sky deliberately dragging their feet? I also read somewhere (can't remember where) that Froome is waiting to be called to Lausanne for PK tests, and the ball is actually in the prosecution's court (LADS/WADA/whoever it its).
I thought that the burden of proof was firmly in Sky/Froome's court now - it's up to them to show that Froome's physiology was playing silly-buggers, rather than the authorities proving that he reacted normally to an excessive dose. It'll end up in CAS whatever.
