Throw in situation:

[DownTownTonyBrown]

Good question. All I can find along these lines are the casebook plays .... the way we interpret the rules.

I didn't read the entire thread so I hope I'm not repeating too much.

See CB 7.6.3B, page 55 of this season's book.
During an attempted throw-in, A1: (a) holds the ball through the palne of the end line and then passes it; (b) steps through the plane (makes contact with the floor inbounds) before passing the ball to A2; or (c) holds the ball through the plane and hands it to A2. Ruling; A legal throw-in in (a), but a throw-in violation in (b) and (c).

Held ball situation comes a little later in CB 7.6.3F, next page.

CB 7.6.3A shows no violation if contact is by Team B

Are these interpretations firmly supported by the rulebook??? Inadvertant/unintentional handoff to Team B - okay, good defense. Intentional handoff to Team A - not okay, violation. I think several areas of our rules have built-in contradiction.

The casebook often helps with these types of questions as they are an EXTENSION of the rules and more precisely show us their intent.
