I was just coming back to paste the link to this one (he starts talking about it at the around the 23 minute mark):
James Patrick remembering Rick Jeanneret and how the Sabres look this year - Sabres Live
I got a kick out of him mentioning Guy Carbonneau, not exactly my player comparable but I get what he was saying. If Krebs' asperations of becoming a top 6 guy fall short, he'll definitely need to transform his game, and Patrick is pretty convinced that Krebs will be able to find a role.
Being old enough to remember, the Habs sent him to the AHL specifically to work on molding him into a defensive player. It's not like he came to that all on his own. But Krebs bringing energy and being defensively responsible would be a continued way forward in his career.
