If we are going to rely heavily on rookies, we have to expect such things from players like Cooper Prat on occasion.
All of those things Pratt did are teaching moments. Murphy should have held conversations with the kid when those things happen. Making an example of him like he did was a mistake, and in the end, made Murphy look bad. Actually made him look like a bit of a jackass. His explanations in the post game presser did him no favors either.
It was a mistake on Murphy's part, that likely cost us the game. Hopefully he has taken some stock in this fact, and gets better in the future. Not holding my breath though, he is one stubborn SOB at times.
