In the Starting Line-Up
That's a great video showing how OBJ catches balls one handed. See how the tight end moves his arm/hand in the same direction as the balls going? That's how it's done. You lower the collision speed of the ball with the hand. That's all OBJ is doing with the one handed catches. And the grippy gloves really help as well.
Catching it with his right hand with the ball arriving from his right side (backhanding) seems to me to require an extra amount of hand-eye coordination / timing as compared to only decelerating the ball over a longer period of time by matching its motion with your hands, which is the normal method for a one-handed catch.
