In fact, his first contact with the playoffs came last season when he played six games for the Philadelphia Flyers in an Eastern Conference First Round loss to the Washington Capitals.
"It was great last year to get that experience," Gagner said. "I felt we were playing playoff-like hockey even leading up to the playoffs, so that was important as a step in my development.
"Regardless of whether you're a young guy or a veteran, you've got to keep learning, trying to get better. So I feel like there's a lot of room for improvement. At the same time I feel comfortable in those crunch-time situations. I enjoy them.

Gagner, who signed a one-year, $650,000 contract with the Blue Jackets on Aug. 1, has been a bargain, tying his NHL career highs in goals (18) and points (50) in 81 games mainly playing on the fourth line.
He had 16 points (eight goals, eight assists) in 53 games for the Flyers last season and played nine games for Lehigh Valley of the American Hockey League.
His value was evident during the Blue Jackets' record 16-game winning streak from Nov. 29- Jan. 3, when he had 16 points (seven goals, nine assists), but Gagner followed that with a 30-game goalless streak.
"He's crucial to us," right wing Cam Atkinson said. "He's been playing well as of late, making plays. That's his mojo. We're going to need him, obviously, to come up big for us in the playoffs on the power play."
