I'm an admitted bandwagon fan who watched a little bit of hockey in the 90's Roenick/Chelios era, but didn't start watching semi-regularly until last season. As I'm starting to pick up some of the strategies and intricacies, I have a few questions that I'm hoping someone can answer. 1) What does it mean to have the "last change"? The announcers make it sound like it gives the home team an advantage to pick their matchups, but if the other team doesn't like the matchup can't they just make a line change at any time to adjust? 2) How are +/- stats calculated? I understand that they are the differential in scoring while the player is on the ice, but can't that be deceiving if someone is involved in a lot of power players or penalty killing. For example, wouldn't a player on a penalty-killing line be at a disadvantage because his line is more likely to be scored on? 3) If postseason hockey can survive just fine without fighting, why is it necessary in the regular season? I really don't understand the two seperate sets of rules. Either allow fighting or don't, but it doesn't make sense to change the rules once the playoffs start.
