Yes, Schlegel's reaction was pure garbage.
I'm all for emotion in sports but I'm also for showing some class. I guess I was taught that there's a right way and a wrong way to act when winning. Also, in addition to that, I like honesty in my athletes - I don't want them to be robots. And I will admit, Shafer's reaction was honest in relation to how he was feeling. Doesn't mean that I thought it was classy though...and I'm glad that he admitted it might have been a little over the top.
Just as an add-on, many people keep complaining about the PBA going down the toilet because of a lack of emotion/personality in the players. When the PBA was at it's height, Earl Anthony was king and that man never reacted like Shafer did when he won...It's not the players bringing the PBA down.
