How would you call these situations?
 

#1: A1 has possession of the ball, but is on his knees and would be on all fours, but he's got his two hands pinning the ball down on the ground. A1 "stands up" so that now only his knees are on the ground. My partner called traveling, but I wasn't so sure. I went with his call of course and continued. Was my partner correct?

#2: A1 drives baseline side from the corner. When A1 picks up his dribble, he realizes he is too far underneath the basket to go straight up with a shot. B1 has moved in behind A1 and established LGP. B1 has his arms raised not straight up, but closer to straight up than he is 45 degrees. A1 jumps backwards into B1 to attempt a shot. Is there a foul here, or is it a no call?

My guess would be PC if anything.

Yes. You cannot get up while in control of the ball (without a dribble). I would consider the player in control of the ball

Likely a foul, but I would have to see it. Technically the defender cannot be in the vertical space of the shooter and any contact would be on the defender. But if the shot was not affected (not likely) and the contact was minimal, then I might call a foul on the defender. Also keep in mind, the shooter cannot jump directly into the defender either, so you might just have a no call. I think this is just one of those HTBT situations.

Peace

the player was on his/her knees and straightened up still on their knees? Why would this be any different than laying on your back and sitting up? It's not illegal to touch the ball to the floor. I've got nothing if I am picturing the play correctly.

The way I am reading this is that the player lifted the ball from the floor and is kneeling not standing. If I read it correctly then a violation has not yet occurred. After all he has his ;) pivot knees. :D

1) No.
2) HTBT - but often, nothing.

What does HTBT stand for?

had to be there

Ah ok, thanks. I've seen it a bunch, now I know what it means!

I'd have no travel here.

I'm not getting out my protractor, but I'm not likely to bail out the offense here. No call (if the defense is not disadvantaged) or PC.

I've got nothing in #1 until he tries to actually stand.

On #2, it depends on where the contact is. If jumping into B1 dislodges B1 from his location, it could be a PC. If the contact is mainly on the torso, I'm not bailing him out. If the contact is on the shooting arm and affects the shot, it could be a foul, but it's going to have to be obvious.

Batteries not included.
 

And I thought that I was the only one who had a needle, an extra whistle, and a protractor, in my warmup jacket pocket.
