If so that does NOT take away Zach's job which is the same for every out of bounds defender under the other teams basket in defending the ball. Do not let it go where you don't want it. This is a basic expectation that starts much younger than high school. Matt I believe was out of timeouts and playing the worse thing possible being a tie should have resulted in an OT win for Purdue. A 3 ball beats Purdue, but overtime against a team that has played one extra game and has fouled out some players should have been in Purdue's favor. When the TOs were exhausted and the teams walk out and Wahl as you say is now taking it out of bound Zach still has him and if Zach does his job the game is over.
As far as we know the read may have been what does Zach do? Purdue can't dictate who takes teh ball out if Zach is a read. If Zach plays the usual one man zone then we now have an extra screener as I stated previously on the perimeter to get a shooter a good look that might go for a 3 ball since the rule of thumb is go for the win if all things are not equal and they were not, Purdue had some advantages. So no matter what Zach did they could use his lack of quickness against him. Course if he does what is expected...none of this happens it is that simple. With all the errors of players in this game to pretend that Zach not doing his job was bad coaching when probably most if not all coaches would have played it the same way is foolish. BTW, why did you have to change your name to post? You probably have a collage of interesting takes under the name your refused to use
