Double Dribble?

[Hawks Coach]

Initially I had a hard time with allowing a new dribble if the ball was already picked up and the bobble is slight. However, I also know that if B1 hit the ball free and it struck the floor, a new dribble would be allowed. It is not clear that this situation is any different - in both cases, B1 causes A1 to lose player control. In either case, i would recommend allowing the dribble because B1 caused a loss of player control, regardless of how slight that loss of control was.
