Yes, I definitely remember Mike Craig, he was one of the original Dallas Stars (when the team moved from Minnesota).
As for Gregor's history here in the States, I really don't know what happened after he left the Stars.
He didn't leave the Stars by choice. He was the victim of an organization that didn't do much to develop young talent. He was one of about five players that had an extreme amount of potential and Dallas just let them go.
There were just too many forwards in front of him who had been around longer and needed to move up. Dallas couldn't use all of them so all but one or two weren't re-signed or traded.
