When asked about Rundblad, Ottawa GM Bryan Murray had this to say: “When we traded for him, we knew that he was a good player. We gave up a first-round pick wondering if we could get that good a player in the draft last year and we felt we couldn’t. He went back and he played extremely well. He’s a high-skill guy. I think the fact that he was able to play where he played was great. The other thing we knew is that he was going to play for Anders Forsberg, who had scouted for us prior to that. We knew he was going to get lots of ice time, lots of development and, obviously, he did a heck of a job.”
2011-12: Rundblad made his NHL debut with the Senators, playing primarily bottom-pairing minutes. He was traded to the Phoenix Coyotes in mid-December for center Kyle Turris. In 24 games for the Senators he scored 1 goal with 3 assists and was minus-11 with 6 penalty minutes. Rundblad made his debut with the Coyotes in December and appeared in one other game before being demoted to AHL Portland in mid-January.

2013-14: Rundblad appeared set for a breakout season after a strong camp with the Coyotes but saw limited ice time in 12 games with Arizona — more times than not being a healthy scratch. He was sent to AHL affiliate Portland for a conditioning assignment before being acquired by Chicago in March 2014 in a trade. Rundblad skated in five late season games for the Blackhawks. In 17 NHL games between the two teams he had 1 assist and was minus-4 with 6 penalty minutes; averaging 13:45 minutes of ice time. In six AHL games with the Priates he was minus-3 with 4 assists.
Rundblad is an offensive-minded defenseman with good size and excellent skills. He has good vision and carries the puck with confidence. A top notch player on the powerplay, Rundblad’s best attribute is his ability to distribute the puck quickly and efficiently while also being able to launch a hard point shot. Rundblad's defensive game, while not his strong suit, has improved since he first came to North America.
Rundblad made the Blackhawks out of training camp and appears set to put the lost 2013-14 season behind him. With so many talented defensemen in Chicago's lineup it is not likely he'll see the type of minutes envisioned when he was the 17th player taken in the 2009 NHL Draft. But his skills have not diminished and he can contribute supplemental offense in the right situation.
