Yes it is.
Advantages...well we get to see the best match ups in the NHL.
Disadvantages...well so much competition in the division that it's going to be hard getting a playoff spot. Right now, if we assume Ottawa will completly dominate and hold onto the first spot in the division, only 5 other playoff spots will be up for grabs since the other two will go to the leaders of the other two divisions in the Eastern Conference.
If you do the math, the odds are slim for the remaining four teams in the Northeast clenching a playoff spot when there's so much competition in the remainder of the Conference.
