Because that literally has no use in any other sport ever. What I know for a fact is that cycling goes to greater lengths to regulate doping than any other sport in the world, and then people accuse it of being dirty when they actually find people. Seriously, where is the parliamentary enquiry into Guardiola, given that he was pinged for nandralone as a player, his Barcelona team were widely implicated in the Puerto affair and whose Man City side have been fined for missed drug tests?
Why is it that you, and indeed anyone else, is happy to brush all of that under the carpet? The sport has a long history of doping, and it's amazing how few players complain about the number of games any more. It's almost as if there is some secret to their recovery, because the better you recover...
I won't hold my breath whilst you campaign for footballers to have a biological passport though.
Actually, you'll find on here that I've laughed at how Lionel Messi was allowed to dope pretty much openly to become the player he is. Hilarious in fact that it's basically never brought up. The idea footballers don't dope is as stupid as the suggestion no gay footballers exist.
But the difference is it's a team sport versus a largely individual one. Track and field has doping issues too (obviously). Loads of other sports do (obviously), but the difference with cycling is this constant, ludicrous holier than thou attitude that everything is great now and the 'heroes' of the day are definitely not doping and that anyone who suggests as such is bitter or uninformed (see your comments on Kimmage - bitter, twisted, simply for highlighting the ludicrous and obvious.) You get the odd Usain Bolt that is idolised, but generally with track and field there's an air of suspicion that is allowed to exist. If track and field catch a high profile cheat, the community don't turn around and go "well, that's the last of that for sure!"
Am I an armchair observer? Yes, absolutely, but in this instance I can say I'm probably
more informed because I can objectively look at the situation, because I don't love the sport and get blinded into wanting to believe in the 'superheroes'.
I'm not criticising the cycling governing bodies as well by the way - I'm saying that they have absolutely no chance of sorting it out, because it's ingrained. If they can see a way to cheat, they'll cheat. You know why? Because the rewards to doing so vastly outweigh the negatives - win a Tour de France and get away with it and you're set for life. Finish 2nd? Nobody gives a toss. So you have to
win, so you'll do anything to win.
As said, by all means love the sport - it has high drama, amazing athleticism, it's fantastic. But don't delude yourself into pretending everything is on the up and up and that it's legitimate competition, because the reality is there's probably some fella finishing 20th every race who's better than the 19 who finished ahead of him but wasn't competing with what is a real life cheat mode activated.
