In the Seven Deadly Sins book about Lance Armstrong and the Tour de France, when there were a series of people caught for doping a few years earlier and there was going to be a new, cleaner Tour, yet the average speed and times shortened significantly afterwards. When Lance was sprinting up a mountain and doesn't even look tired, maybe it isn't right.
Liverpool vs Man City felt a bit like that for me this year, especially Bernardo Silva:

Silva is referred to as 'Superhuman', a 'man possessed' and 'he's probably still running', but no one asks how it is happening. He ran 13.7km and had four interceptions, while still being fit enough to keep going on a technical level and not lose the ball. There were several players in that match running like that while keeping up the skill that didn't look tired, the game was so fast I found it hard to believe. Don't mean to just pick on Silva, but just an example of how performances like that are covered.
