Not really. Its pretty easy to tell what riders fluked a podium or even a win. Lately, you can point at riders such as Hugh Carthy and Jack Haig for example off the top of my mind who are riders that podiummed, but it was obvious that was their ceiling in races where everything went right.
Then again, Tao G and Hindley won GT's. I thought they both were flukes in 2020, and while Tao hasn't performed really, he looked extremely good and ready to contest the win in 23 while Hindley won in 22
Haig and Carthy did not podium the TDF.
