Patrick O’Sullivan of the Edmonton Oilers is looking a bit rough these days. In his first full season in orange and blue, he’s been little more than a burden to the NHL’s last place team. While Edmonton as a team share a number of “worsts,” O’Sullivan too finds himself at the bottom of a category that he’d rather not be able to boast about. At minus-32, he is ranked 849th in the league in plus-minus…out of 849.

O’Sullivan is having a brutal season with Edmonton. He’s four points behind Shawn Horcoff for second-last in the league in plus-minus, and with 10 games left in the season; it doesn’t look like things are going to get any better for the beleaguered Oiler. He’s no Bill Mikkelson, but O’Sullivan certainly can’t be happy with his league-leading statistic. In four NHL seasons spent in Los Angeles and Edmonton, O’Sullivan hasn’t managed to stay on the good side of zero.

He was drafted by Minnesota in the 2nd round of the 2003 NHL Entry Draft but didn’t make his NHL debut until 2006 with the Kings. He played 44 games that season, scoring five goals and 19 points with a -6 rating. There was marginal improvement the next two seasons, although he did score 22 times in 2007-08. He was sent to Edmonton at the 2009 trade deadline and has centered the backup lines since.

Nobody wants to be the worst at anything, but in the 2009-10 NHL season, O’Sullivan is getting the unfortunate honors of having the worst plus-minus rating. The team surrounding him isn’t helping much. The Oilers also have the worst goal differential in the league by far. They’ve scored just 184 times while allowing 248 at the other end of the ice. What a coincidence it is that the team’s plus-minus is -64, while O’Sullivan’s alone is exactly half that.
