Yep, I was not thinking, I had all wrong in my head.

I should have added: And this would be both.

So on the follow-thru if a players hand and arms extend out past the vertical plane but a player runs by and hits his arm while he's airborne, this is a foul. But if it's the foot or leg, we just let it go?

Your initial premise is flawed.

The NBA actually made this a point of emphasis the year, I believe. They want more officials calling offensive fouls on players for creating contact with the leg kick on jump shots.

I have seen it called a few times.

In my HS school games I have not seen this much to the extent that a PC was warranted but I have seen a few flops with extending the leg and flopping to make it look like a foul on the defender.

Yes, contact on the jump shot is a POE this year...including the shooter creating contact by extending his leg. In fact, I believe the league has been trying to crack down on this the past couple of years, and I've definitely seen more no-call or offensive fouls call on these type of plays.

I think Jodie Meeks just got away with one in the Clipper/Laker game. Watching live it looked like a shooting foul on Matt Barnes but on replay I think Meeks kicked his leg.

Got away with it and ended up with a 4 pt play.

Just happened with a few seconds left in 3rd quarter.
