It was Vini Fantini that sprung to my mind reading it, and I'd say it's more likely to be the lesser teams, desperate for wins and world tour points (which really needs to be addressed by whoever is incoming President.
And again when he mentioned physiology I was reminded of the anecdote about riders with arses the size of elephants zooming up hills rather than the emaciated specimens we see but hey you say potato I'll say potatoe
It could be either interpretation, or both!
Honestly, obvious is obvious (e.g. Santa, Big Mig, Riis, etc). Perhaps that is all he is referring to.
Then there is the less obvious - riders getting soooo skinny they make anorexics look healthy

. Yet still maintaining excellent overall power (not just power to weight), not getting sick all the time, riding at 95% all year long and still winning, etc.
Being able to simultaneously (and dramatically) improve climbing cols, climbing short walls, TT'ing, and your ability to throw in race defining attacks and surges.
As for team wide doping, it's not all the same. There is team wide acceptance (no cost), there's networking and access (no or little cost), there might be some 'informal' access (low cost and now incredibly unlikely, as the potential costs of $ and team shutdown are so high), to sophisticated doping regimens (higher cost and very high risk but with maximum payoffs).
I do not suspect the old school team-wide, supported doping programs still exist. But sometimes I think there are other ways to enable team wide performance, especially when one can access drugs and methods that are not banned as of yet and when cost is not an issue. I think a team with big enough pockets could look into strategies and supplementation that might not be well received by knowledgeable people, but are not banned methods.
