Victor Orta was trying a Big Brother experiment last season, throwing loads of twenty-somethings in a building and seeing who doesn't break down, but those who graduated to Bielsa's dorm-rooms, video-rooms and round-the-clock attention are not the headlit rabbits we watched freezing last season.
And you can't explain why doing the thing you love or are good at can feel like it's presenting an insurmountable challenge just to begin each day, despite knowing that it's the best feeling you have.
"I never forget looking back at all those people who had got their wish," says Deane. "And thinking, you are not going to beat me. This isn't it for me."
Winning promotion to the Premier League with Leeds United is Pontus Jansson's dream. This season dreams might come true, and Jansson is recognising, after the World Cup made him a latecomer to Marcelo Bielsa's revolution, that the more serious he is, the more true that dream could be.
While Reach's speculative strike had the satisfying audacity of a stunt, Klich made something artful, deliberate and beautiful. It's the difference between watching two magpies have a fight in your garden, or watching a nature documentary narrated by David Attenborough.
The lingering impression from seeing Bielsa take on Pulis was not that one style of football works better than another; neither is going to suddenly change their minds now, anyway.
Imagine turning up to the first home match of the biggest promotion attempt in years, and seeing Vinnie Jones is sitting on the bench, and Mickey Thomas is starting. Maybe that's the real reason fans were smashing windows.
Saiz dribbled towards the centre, swerving through two tackles, and was fouled by the third; he sprang to his feet, offered his hand and pulled the player who had fouled him back to his feet, desperate to play. We were 2-0 down in stoppage time in the Carabao Cup here.
Kalvin Phillips threw himself at the ball to stop Norwich taking a shot at Peacock-Farrell, and it was a moment when Bielsa's principles of complete commitment from first to last combined beautifully with Leeds United's principles of side before self and effort for the cause.
Few players do less to hide their emotions: when Pontus Jansson is happy, he runs to the fans and punches the air, and when he's sad, he turns his entire face upside down and glooms away down the tunnel. If there's any doubt how he's feeling, there will be an Instagram post explaining it.
