While OEL returned to the game after leaving for a short period of time, the play that caused him to be bloodied proves that anything can happen during the Stanley Cup final and you need to always have your head on a swivel. While the lack of a call on the play should be called into question, the referees have a difficult time as it is to make sure each team plays the straight and narrow.
Again, it's still quite early into game one, but if the first ten minutes are any indication about how the series will go, the fans are in for an absolutely fantastic Stanley Cup final.
