If you want to build a team that contends for finals, 2 good players would suffice.
If you want to build a genuine Premiership contender, you need elite level match winners. The opportunity to get the best 18 y/o in the country is doesn't come around that often. That's why you keep Pick 1.
But pick 1 doesn't guarantee an elite player, and lower picks don't stop you from getting elite talent. Just from Hawthorn, guys like Franklin (5), Lewis (7), Birchall (14), Rioli (12) are the kind of elite core players that Saint Kilda could pick up if they trade pick 1. I don't know enough about the talent in this draft, but from i've read, it's not like Petracca is head and shoulders above the rest, and a sure thing to be an elite player.
Saint Kilda could potentially pick up 2 or 3 elite players if they get 4/6/7. Add that to the other early picks they will use while rebuilding, and they will have a great core to go forward with. By keeping pick 1, they likely get Petracca, and still have a huge hole to fill in the KPP department, which this draft is particularly strong in. They have some young, potentially elite, midfield talent on their list, but i don't think they have much in terms of pure KPP's who could be elite.
