Getting on top is much more complex than just getting superior picks.
Draft picks/scouting is of course hugely important but it's only one of several variables that are at play, making smart trades, smart signings, coaching, health, luck, etc.
That's why I never get too caught up in focusing on one specific thing, you need it all and there's really no sequential order or established recipe to follow.
Its literally mostly a series of very fortunate events and the best organizations take notice and are able to repeat those patterns.
