2009-10: Started with Skellefteå J20, scoring 4 points in 3 games before making the big club and playing 47 games with. In his time there, David Rundblad would score 1 goal and 12 assists with Skellefteå. He would also play a role with Sweden’s Bronze Medal Team at the World Juniors, scoring 5 points in 6 games.
2010-11: Rundblad would be acquired via trade in the 2010 draft for the 16th overall pick in 2011. He would go on to register 11 goals and 50 points in 55 games. 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.
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. He was re-called in March and played six games total with Phoenix; finishing with 3 assists and minus-one and averaging 14 minutes of ice time. He was with the Coyotes for the playoffs but did not appear in any games. In 30 games with Portland he scored 7 goals with 9 assists and was minus-18 with 27 penalty minutes.
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 power-play, 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 remains a work in progress and must continue to improve.
Will be in the mix for full time duty with the Coyotes, but may have to prove himself further in the AHL. Offensive ability is NHL quality but he must become more reliable in his own zone.
