Is this a T?

However, if I am bound by the word "possession" in the rule, then I am left with a delay on Team B or blow the play dead and start over.

"Possession" here isn't defined. If A1 sets the ball down for a moment, he's still in possession even if he's not holding it at the moment. To me, #2 is a T.

I'm still not sure on #1, so I'd probably just give the warning; unless A1 was about to pick the ball up, then I'd give the T.
