Rajon Rondo knows he's throwing this alley oop to KG the second it touches his fingertips. Both guys who are back on D are looking square at him. Meanwhile, Rondo knows KG is streaking down the floor. So he just casually pivots and tosses a nice little pass to the front of the rim.
Reward the big guy!
Props to KG for running the floor so hard after the block, too.
