Being the last line of defense, goalies are often so fixated on what is going on in front of them that they forget to remain aware of what is happening behind them. That rarely ends up costing them, but in this case it clearly did.
Some may call this tactic smart or sneaky. Others would choose to believe that it undermines the ideals of fair play and sportsmanship. What do you think?
