Honest, open question here.
Take a look at this screenshot. It’s from right before Raymond Felton drove to the basket, drawing in the defense and giving Jason Kidd the open three-pointer that sealed the game for the Knicks and the final score at 100-97:
Is he out of bounds? I can’t honestly say for sure. From that angle, it’s really close. It’s entirely possible that he’s on his toes, and his foot isn’t touching the line. But it’s also possible that he’s out.
If anyone has another angle, share it up!
