If this team gets healthy and has a great summer... they will come back to be a top 3 team in the west.
Everything else you said was true, but this is ridiculous. No way the Lakers will be a top 3 team. Pringles is still coach, there's no guarantee that Kobe will be Kobe (or when he will even come back), Dwight hasn't resigned yet, Nash is still old, Pau is not young, MWP is a shell, and their shit bench will still be a shit bench.
At best they can maybe be a 5-6 seed behind the Thunder, Spurs, Clippers, Grizzlies, and maybe the Warriors. Bottom line though is thinking they have the potential to be a 3 seed next year is a nice little set up for another first round exit next year. Until next summer, this team isn't going anywhere, healthy or not.
