It was a great shot but putting it at number one is banking heavily on the "feel-good" angle of a D-Leaguer getting a call-up and hitting a gamewinner, before going on to get signed for the rest of the year.
I remember watching that game and freaking out. However, the face that there was like a 40% chance of him making it diminishes it a bit. (Also Crawford's game winner a couple days later was way better)
I was surprised at that too, but I guess they wanted to avoid players getting in the countdown too many times and just picked the one they felt was the most remarkable. If that was the goal, I think they picked well.
