for me greg modernised cycling. Prior to his arrival, cycling was unchanged for decades - european riders on european bikes, backed by euro sponsors with perhaps one or two outsiders having infiltrated the clique. Greg changed things entirely - he was a key player in globalising the sport, getting decent salaries/sponsorship deals wihin the sport and introducing new technologies and ways of thinking.
I reckon hinault's 5th tdf victory was stolen from Greg. He perhaps could have gone for it, but had the sense to know the deep rooted french patriotism and the connections hinault had might have jeopardised his future.
His greatest error for me was speaking out on armstrong. Whether factually correct or not, it smacks of sour grapes. He would have been far better casually distancing himself from LA if he had genuine concerns.
His other error was standing in front of a 12 bore shotgun
