If the ball is on the way down, I have goaltending plus a T. No contact from the shoe on the ball I have just a T. If the ball is on the way up and the shoe contacts the ball, I have a T and ..... ummm, errrr, something else???
Especially in the last few seconds of the 4th quarter and the team ahead by 2 or 3 tries this you have to do something more than a single T. I can't say I agree with 3 technical Free throws. I am more inclined for issuing 2 T's, one for unsporting conduct (throwing a shoe) and another for unsporting conduct (illegally using equipment). Flagrant doesn't solve your problem nor do I think it is fair for the shoe thrower. 2 T's I am ok with, then they aren't suspended for the next game as well. I think we are relatively supported by rules for a contact on the way down and a no contact at all situation, so let's come up with something fair for contact on the way up that we can support by rule. Good luck.
I do think the penalty should be more severe than 1 T though or every team would use this as an end of game strategy to seal a victory.
We should adopt the NBA case ruling. That would make our job easy peasy lemon squeasy.
