You've picked only this season, which is a month old.
The fact is that doping has always been part of the sport I love, and over the years we've had big personalities dominate the sport for a time, from Anquetil through Merckx to Armstrong taking in people like Wiggins, Froome, Contador, Hinault etc and all of whom are proven or rumoured dopers (with the possible exception of LeMond).
Now you have 3 riders who appear so far in front of everyone else (with the possible exception of Pidcock who rides for a questionable team himself) and we're expected to believe they're clean and it's just a coincidence.
Lefevere is a gobshite and would only be shouting from the rooftops if he was whiter than white, which I'm sure he isn't.
100% agree on your last point re football, but it doesn't mean that cycling has suddenly, after over 100 years of cheating, suddenly become a clean sport. To me cheating in cycling is just part of the fabric of the sport I fell in love with as a 11 year old in 1988 and I don't think it'll ever go away.
