From what I have read, it seems like the 2 players DID stop it. If it wasn't for them, Butler most likely would have beaten them up worst.
You have to remember, it was most likely a poor quality video. Think about a cell phone video that is shaking and moving around.
Also as a coach, those are like his sons. He has a responsibility to each and every one of them. Our coaches are not trained detectives, nor should they pretend to be.
Last thing we need is coaches just guessing at who it could have been. I doubt many parents would send their son to play for a coach who did things such as that.
I do not agree with ANYTHING that Butler did, but I do see where our coaches could have been coming from on this issue.
