The UCI is not going to change. Look at today's news from the Polish cycling federation: A one race suspension for steroids? Then look at Weasel's domination of USAC. Then, there's the recent Australian scandals. Pro cycling isn't dirty from the top down. It's dirty from the bottom up (the national federations).
The riders are sheep. They do as they are told.
Pro cycling team ownership seems to me to be, in large part, a toy sport. Guys like Stapleton, Rihs, and Tinkov are operating their toy teams. Those teams are just tools for rich-guy ego fulfillment. Tinkov's and Rihs "see no evil, hear no evil, speak no evil" approaches are utterly ignorant from a long-term sports marketing point of view, but make complete sense when viewed from the "I want my team to win" point of view. Then there are the organized doping teams . . . Liberty Seguros, Astana, etc.. . . . Those teams are not about sports marketing either--they are about "just win, baby." I don't see any change coming from the teams, either.
I don't foresee any change from the current structure. Cycling is going to remain the filthy niche sport that it has always been.
Now if somebody starts up a competing and professionally run league . . .. Then the existing pro racing structure will have to either shape up or die.
I'm not rooting for any changes at the UCI. I'm hoping that they fail, right and left. Maybe then somebody truly professional will start competing with them.
