screening a player from the ball?

[Troward]

A1 attempts a shot that misses and rebounds off the floor inbounds and is heading out of bounds slow and high. A2 on the baseline is close enough to the ball to make a potential saving play. B1 jumps in front of A2 to cut him off from the ball.Both players are moving and there is a slight collision, but A1 is still able to try to side step arround B1 to make a play on the ball. However B2 slides with A2 (like he is boxing him out) preventing him from getting to the ball to try to make a save. I NO called the scenario. Team A coach is all over me for an illegal screen which planted the seed of doubt that there might be something illegal in this play. Any opinions?
