Kelvin, that's what I said last year in our thread on this.
I will add that the moment to assess whether or not there is a team in control is just prior to when the player jumps. In other words if his team is not in control when he left the floor, then he should not be penalized for a backcourt violation, if he caught the ball while airborne and then landed.
That is what I had contended. It is clearly NOT what the NFHS was thinking as we can see from the new casebook play. Oh well...
