For the past several years the folks over at ESPN have published a "Future Power Rankings" that tries to express how they feel each team is set up for the next 3 years.
It turns out that the Celtics came in 10th (with the biggest jump of any team in the league) which puts them just ahead of the Wizards and just behind the Jazz and Thunder.
Chad Ford and Kevin Pelton were the ones that came up with these rankings and they scored the Celtics high on the draft (quantity of picks) and management (which included Brad Stevens and Danny Ainge both getting high marks).
