From TSN.ca:

Karlsson, 21, is in the final year of his entry level contract and with a cap hit of just US$1.3 million is considered a bargain.

But there's no doubt the Senators will have to pay more to keep Karlsson. Earlier this year the Tampa Bay Lightning re-signed Victor Hedman to a five-year contract extension reportedly worth $20 million.

"I was happy for him and he's a big part of their team and he deserves that contract," Karlsson said of Hedman. "It's good for him and hopefully I can get something similar."

Umm... If Karlsson is happy with "something similar" to 4 million a year for five years, Brian Murray needs to put a pen in his hand before his agent convinces him that he could probably make almost double that. This would be an absolute STEAL of a price.

I know he was probably speaking in diplomatic terms... It wouldn't look good to say to the press "It's good for him and hopefully I can get something way better," but still...
