To me the simple thing is that the TUE system has to be changed and Froome is a perfect and simple example : he only used it twice in 9 years it seems. My point would simply be, why then did'nt he retire from the 2014 Romandie and the other race to be healed for what he had at the time ? It surely wouln't have broken his career would it ?
There could be many less TUEs, or rather most of the those TUEs should have been assorted with a work stoppage period : the doctor prescribes a medication allowing the athlete to get better, in the meanwhile, he rests.. This is exactly the same impression I had yesterday with Serena Williams' shitty 2014 spring with lots of med : just stop competition, get your TUE to get healed and then go back to the sport... That would be so much simpler.
