Gregor was originally drafted by the San Jose Sharks in the fourth round of the 2016 draft. Now 25, he was not qualified by the Sharks after playing parts of the past four seasons, including 57 games in the most recent campaign where he put up 10 goals (a career-high) and 17 points.
Similar to recent signing Simon Benoit, Gregor comes from a bottom-feeding team. The Sharks never even sniffed the playoffs over the past four seasons he was part of the organization. His most recent linemates were mainly Nico Sturm and Nick Bonino in a defensive zone start-heavy role.
