Here's a little known fact about Anthony Davis: he has the longest arms in the history of arms. I'm not sure if this is an actual fact, but it sure as hell sounds like it could be one. Therefore, I'm content to go through the rest of my life believing that Anthony Davis has the longest arms.
Look at how he goes up and effortlessly finishes this left-handed alley-oop. It's amazing and a little bit terrifying.
