If I distill the various accounts by ex-riders, eg: Trent Lower fiasco, or Rohan Dennis' desire to gtfo asap, the fact that someone like Millar was so lauded, the dodginess of Ryder and Wiggo's rise to wtfery, etc, etc, I would say this:
Some pro riders are just happy to have a spot on a team. You don't have to pay them, and definitely do not have to coach them, feed them, and in some instances, even pay them.
Add to that a doping ban, and the rider, I am guessing, gets diddly squat from JV / Garmin. Other than internal testing. And some weird process whereby if they catch you with dope you're fcked.
JV gives me the impression he does not care. Maybe, if you were a friend, but at a guess those people are already loaded and would not need anything from him in terms of assistance in the first place.
Sky talk about doing a bunch of stuff and for the most part I think it is BS. See Froome's lack of testing values or wind tunnel time. JV doesn't spruik stuff like SKy do and doesn't do it either.
Start of year camps, yes, coz that's where you get sponsor coverage and the media rock up and schmooz, but otherwise, as for the riders's doping programs ... er .. I mean preparation, pretty much left to their own devices.
IMO of course, as always.
