DALLAS -- Buffalo Sabres general manager Jason Botterill can't hide his excitement about the chance to select Rasmus Dahlin first overall in the NHL draft.

Botterill says he's as impressed with the Swedish defenceman's analysis of his game as his dynamic playmaking skills on the ice.

Dahlin could become the second Swedish player taken with the No. 1 pick after Mats Sundin in 1989. Sundin went on to a Hall of Fame career. Dahlin is projected to be a franchise-altering piece on the blue line. If he goes to the Sabres, he can help centre Jack Eichel and provide a spark to Buffalo's offence.
