Already easily, the best on ball defender in the game.
Has a quality 3 point shot to go with a pull up jumper.
Good at finishing around the rim.
Reliable midrange jumper.
Great athleticism, speed, and acceleration. Better than Rondo's in all three, and Rondo is known for his quickness.
Not the best handle, nor the ideal stature for a 2 guard, but certainly a star in the making. He's displayed and shown all of this despite being the #5, arguably #6 option last year , as well as never having ONE real training camp or for that matter, a real season's worth of practices due to the Big 3's age. Kid is already a defensive stalwart, but he's 25 points a game waiting to happen. Pierce in an interview said that Rondo was the only one who could stay with him. I can't wait until he really blossoms and enters his prime and is given time to polish his game.
Credit Ainge for a massive steal.
