Erik Karlsson, it seems, is good for at least a point every night.

But the fact is, heading into Tuesday's meeting with the Florida Panthers, the Senators star defenceman had been held off the score sheet 25 times this season.

That only makes his totals more remarkable.

Karlsson extended his consecutive-game point-scoring streak to eight by setting up Mark Stone for second period goal against the Florida Panthers Tuesday.

Entering the night With 20 goals and 48 assists through the first 71 games of the schedule, Karlsson had a shot at becoming just the third defenceman to average a point a game in at least 16 years. (Could be longer, but the NHL has only kept numbers on its website since the 1997-98 season.)

Only two defenceman have been point-a-game players since then. Mike Green accomplished the feat twice, scoring 73 points in 68 games during the 2008-09 season and 76 points in 75 games in 2009-10; and Nicklas Lidstrom had 80 in 80 in 2005-06, the only time in his 20-season career that he averaged a point a game.

Karlsson broke the record for most goals by a Senators defenceman he shared with Steve Duchesne Monday in Tampa.

"Obviously it's an honour, in a way," he said when asked about the new standard Tuesday morning. "I'm happy for myself of getting there, it's something I want to achieve.

"I would have traded all that for a better standing in the standings, but it is what it is. It's just one of those small things that maybe after the season, you take some pride in."

Asked about his own personal stats goals Tuesday morning, Karlsson was coy.
