It's really not. Both teams sucked for a while, drafted well, and managed their assets skillfully (locking up their core while acquiring complimentary players along with a few top talents).
Both teams are in a bit of trouble cap-wise. I actually think the Kings are a little worse-off than the Hawks. The Brown and Richards contracts look borderline unmovable. I know Brown is actually contributing, but 5.75 for a 20 point player is pretty ugly. The Hawks can unload Sharp, who was largely unproductive in the playoffs, and Bickell. It'll be interesting to see what happens with the two bigger RFAs for both teams in Toffoli and Saad.
