Not sure about a 36 year ref

[seohio]

I was doing a 3rd and 4th grade game today in which I don't really like to do because alot of these coaches watch Roy Williams and Coach K and somehow become super coaches. I had a ball roll over the top of the rectangular backboard and when it rebounded it rolled off the back..I called the ball out of bounds. A little while later I noticed a older fellow setting on the frontrow and had a offical over there and pointing at me, so I walked over and this ref met me before I got there and told me the guy was complaining that the ball wasnt out of bounds. So I approached him about it and he informed me the ball wasnt out of bounds and in front of people told me I didnt know what I was doing and that he has been a ref for 36 years.I asked him sir. do you have a rule and case book and he just smarted something off. I told him I would be glad to show him in these books why I felt this ball was out of bounds but he would rather try to belittle me.so, after the game I was waiting on him with my rule book in hand rule 7.1.2 sub b and my case book in my pocket. He hurried to his car and ignored me and sped off.am I wrong on this rule????? was it not out of bounds? He told me I was talking about a fan shaped board and I dont understand how a ball could roll on a fan shaped board.
