It's hard for me to not think of this move as leverage to get rid of Vino and nothing more (other than a bit of grandstanding at an appropriate time to appear tough on doping). I think it's a positive step for cycling that this is going forward, even if it might have the effect of giving the subtextual message 'come on guys, you can't dope like this anymore, you have to be smarter'. Fill in whatever blanks you can with Sky and speculate about whatever they're doing that works, but the Astana system has like FIVE POSITIVES in the last year. They've halfheartedly distanced themselves from those 'individual' riders, but not vociferously enough to miss their own home race by asking for Iglinskiy's B-sample ASAP. Anyway, all I mean is that yeah, there are lots of problems in cycling, but this is the barf on your floor that you have to clean up before your houseguests come over, not the rats in the wall that you try not to listen too hard to and hope they're actually just other sounds. Cookson had to address this first because it's the most obvious and popular move.
Given his altered approach to broadcasting doping positives (the 'slip 'em in a report and let the press find them if they want to' approach rather than the McQuaid 'publicize loudly how hard you're working on anti-doping to silence uncomfortable questions' approach), I also can't help but speculate that Cookson is calculating that this is the path to follow to get ahead of the story (Padua, CIRC) so that he can say 'we've already eradicated some of the problems brought up here, guys!' to minimize the fallout/distract lazy press members from looking at harder questions. And, as far as the endgame goes, I think the UCI is walking a tightrope where they don't want to discourage sponsors and don't want to have the reputation for putting whole teams out of work mid-season, but also want to send a message that money and stable sponsorship won't protect you if you dope stupidly. Vino's at the center, with his problematic public history as a rider, and seems like the neatest target - it's not hard to imagine the message to the Astana sponsors as 'listen, get rid of him, some other problematic team managers, and pay a fine, and we're back to square 1'. The ball is in the Kazakh court.
