Foul on throw in
 

Studying the throw in tonight, wondering if Im understanding this correctly.

I know If B reaches through the plane and touches the ball its a T, or fouls the thrower its an intentional foul. Also if the thrower holds the ball over the court B can bat/grab the ball but what happens if B fouls the thrower on his/her arm while his/her arm is over the court. Is this still an intl foul or a common foul?

Common foul.

We had a thread on this a year or so ago. The consensus was that it was a common foul.

I believe that it was a question on the California Basketball Officials Association study guide. The answer provided said common foul.

Rule?

Look at it this way.

You've got a live ball foul. What rule says it should be anything but a common foul?

Correct. The rule only states that it is an intentional personal foul if the defender crosses the boundary plane. In this case the defender didn't do that, so that ruling doesn't apply.

Strictly speaking, a defender that reaches across the court boundary and fouls the inbounder while he/she is completely on the out of bounds side of the court is still a "live ball foul", but it is intentional, not common. ;)

Unless, of course, I've misunderstood something. :)

Yeah, you missed this part. :)

Yes, it's a live ball, but there is a specific rule that makes it intentional rather than common. That specific rule doesn't apply if the thrower reaches across the line and is fouled by a defender who does not reach across the line. That was my point.

I specified live ball to differentiate from a dead ball contact foul; not part of the OP, but worth distinguishing in this discussion, IMO.

I missed that point.:o I failed to realize you were talking strictly about the situation as described in the OP.
