It is, but usually - or better say in our storied past - it was about developing exceptional youngsters into world beaters or even all-time level talent. Our normal template is to take a Greenwood-level talent and nudge them on to world class for a career. In the here and now, Yoro is more akin to what our policy normally is, not Hojlund.
Suffice it to say what we're more known for is bringing in young players who have exceptional and easily identifiable aspects and attributes and then rounding out their game, so basically bringing other elements in line with what got them through the doors in the first place, as well as taking their initial selling point and making it elite in its own right.
Hojlund is a massive deviation from the template we're renowned for. In our true form, it is a player like a young Isak that would have come through the doors and be turned into the very best version of himself possible, not a Hojlund.
Whether you like what you see in Hojlund or not, there's no real consensus on the player he is or the player he might go on to be. There's a lot of hope based off not very much, but not much tangible elite ability, and that's a big departure from buying or promoting what would be classed as S tier talent.
A better way to say it might even be we're not used to developing players who are starting so far behind the starting line to becoming anything - usually, you have something really special about you for us to fork out eye-watering amounts of money. That policy has floundered a lot, the past few years, but it's still very foreign to the fanbase, which is why all the overpriced that have come through the doors of late have been getting a lot more stick: Antony, Mount, Hojlund, Zirkzee are a departure from: Pogba, Martial, Sancho, Amad and even Memphis Depay, so it's a question of what's coming through the doors in the first instance and where they're needing to be developed from rather than us not being familiar with putting the finishing touches to talent and making it something better than it was (historically).
