On Jan 12, 2008, the Ottawa Senators completed their 43rd game of the season, and had a 29-10-4 record. Wow.
They finished the regular season 43-31-8, and then bowed out in a 4-game sweep at the hands of the Penguins.
If you do the math, that means over their last 43 games they had a record of 14-25-4. Ouch.
