Okafor is a budding elite NBA player.
His combination of agility, quickness, strength, and skillfulness on the offensive end is reminiscent of, Celticsblog favorite, DeMarcus Cousins; except, he's in the first year of his rookie contract and can be reasonably expected to acquire strength, skills, and the wrinkles to better utilize them in-game.
The answer isn't obvious today because of Okafor being a rookie and the CB lust for a defensive+rebounding Center, but this thread will be looked back on as an "Ibaka or Cousins?"-type thread even if Noel improves.
If the cost to acquire Okafor or Noel were equal, Jahlil is the player to acquire, easily.
Since when is Okafor quick or agile? Dude moves in slow motion.

In the very first clip, he's beating the 2014 DPOY off the dribble with a quick first step, getting to the rack, and dunking it.
What Okafor exhibits in that video and others is agility and quickness, in addition to the other attributes mentioned. He's facing up 4s and 5s, taking them off the dribble, making quick moves, and gaining position on them without utilizing brute strength.
If he's placed on a scale in relation to his size (compared to players 6'11 and up), he'd be above average agility and quickness-wise.
