Rules Change?

[Junker]

I had a situation last night in a boys V game that made me want to see the fed. change a penalty. We had a good game going. Visitors (B) were down 15 at one point in the first half and came back. At one point B had a throw in under their basket. I'm administering the throw in. B1 throws the ball inbounds, runs the entire lenghth of the baseline oob, steps in and hits a shot cutting the lead to 4 or 6. I booted the call and used the new violation penalty on this (I've had conversations with an assignor and some other officials on this) when by rule it's a T. My idea is to change this to a violation as well. A T at that point in the game would not have improved our game in any way, in fact, it might have really gotten the visiting coaches on our butts, but the player clearly gained an advantage by staying oob. Any thoughts on changing this play to a violation so we don't have to consider the game managment end of calling the T? By the way, I apologize to all officials for administering the penalty wrong. I don't think I've ever misinformed a coach on a rule like that and I'm kicking myself today for doing it.
