Davis reminds me more of Tim Duncan than Kevin Garnett.
As others have said, though, perhaps he's more like a mashup of the two.
In any case, he was already really good last year when he was healthy. This year he's taking the league by storm.
The Pelicans are going to be just fine long term. Holiday is a perfectly fine point guard, and Davis, as long as he stays healthy, is a superstar big man. Defensive stud who can also score.
The NOPEs just need to add some depth, especially on the wings, and they'll be golden.
I think they probably need to trade Gordon for a couple more reliable pieces though.
