I have never heard of such a thing as de-training before today when Yates mentioned it (resting/training lightly the last week toward a GT) and then not really putting in big efforts in the first week apart from stage 9 (and the 12 minutes on stage 1), but it somewhat made sense to me. I think its a thing you at least gotta consider when training for a GT - if it has a light beginning, you can maybe go a bit harder the week leading up to the event.
Lopez, Landa and a few others were also "detraining" and that's why they cracked in San Marino? I think the explanation lies in 200km + stages apparently boring and easy but with lots of bad weather, about 15.000 m elevation combined (didn't check but read somewhere), a few light crashes for some and then the big day in San Marino with real bad rain, weather and a brutal effort. The hard men survived, Roglic proved to be tough, Nibali we knew and suprise Mollema. The others didn't, Yates the most striking example.
