martinvickers said:That's not the choice they faced. Complete hindsight red herring.
By your lights what they must have had, prior to Vuelta was
1 grupetto rider approaching end of contract.
1 jar of super special sauce to get from 0 to GC in 6 weeks.
The choice you are implying they actually had, at that time was
a) drop and sign someone useful - cost, re Froome - nil
b) signed, then 'super' juiced - cost, re froome - well, new GT GC candidate for grupetto peanuts
b) 'super' juiced, then signed - cost, re Froome - paying a small fortune for former grupetto, p*ssing off your existing numero uno, and spreading 'the secret sauce' to s/o who might just walk off to another contract elsewhere with his new found superpowers.
And you're telling us the new leaders in strategic doping chose c).
Oooookey-dokey. Continue.
Bingo - I couldn't have put it better myself.
