Nothing. Play on.

I'm not talking about a play where establishing team control is an issue. I mean controlled in the sense that the player meant to tap the ball inbounds and didn't merely lose control of the ball or never obtained control of it.

I figured you knew this...just like a "tap" with .3 seconds left in a game. It is not "controlled"/secured therefore, a FG can be scored.;)

Abs??
 

Like others have said, HTBT... If the kid was acting like a jerk, this could be the last straw. For me, I guess it depends on what, if anything, the player might have done earlier in the game... I'm not sure just slapping the ball would warrant a T, but it might if there was more to it.

I T'ed a kid this year because he threw the ball at me... sort of. It was mostly an ABS.

I had called an off-ball foul (on a different player) and was going toward the table to report and the ball bounces off my shoulder -- hard bounce-pass, at me, apparently. I continued with my report and then turned around to warn the kid, only to find him arguing with my partner about what he did.

I wasn't going to, really, I was just going to warn him. Never mind. Whack. He'd had a bad attitude and was whiny about several calls already. Enough.

Coach: What did he do?
Me: He's had a disrespectful and unsporting attitude toward both me AND my partner all game... and he threw the ball and it hit me.
Coach: Really?? Sorry.

The kid sat for the next quarter and a half.

On the OP, for me its factors....did he have attitude doing it?, was he responding/payback to you/crew for something he disliked previously?, could he have simply been tired/winded and that was the way his body just happened to move at that moment?. There's a whole slew of X factors there....factors and judgment , that's what I would boil it down to, so I have no say as to what I would do, because I wasn't there to see all of the game to be able to say how/what to call.
