Continue to talk among yourself WSU fans and attempt to justify the behavior. I for one (and I know that there are others as well) have found this to be quite humorous as long as no WSU players were truly injured.
Marshall had a major meltdown - he should have simply called time out and walked over and told the other Coach that he is pulling his team from this Exhibition and walked off (it wasn't going to hurt the precious RPI). To me it was much like when Knight had his epic meltdown that led him to throw a chair across the court this will always be part of his legacy now. It doesn't mean he isn't a great coach / recruiter etc it is simply another side of him that isn't all that pretty.
