Redden ended up losing out to Sydney youngster Dan Hannebery. Redden earned his nomination after what was said to be an "outstanding" performance in a narrow loss against St Kilda.

This caused Redden to be ranked 9th on the all-time list of most tackles in a season since statistics for tackles have been counted.
Redden is said to play a crucial role in the current re-building process which the Brisbane Lions team is undertaking. In this reference, Redden is listed alongside Tom Rockliff, Todd Banfield and Daniel Rich who are considered important to the re-building process. Teammate Matthew Leuenberger is also another player who is excited by the future of Redden and co.
Redden has not missed a game since his debut in round 15, 2009.
Redden was listed to be Brisbane's most underrated player in a club-by-club analysis of the most underrated players by Fox Sports journalists John Clark and Paul Pickering. Redden was noted to "rarely earn the plaudits as peers Daniel Rich and Tom Rockliff".
With club legend Simon Black considered to be on the back-end of his career, Redden was also considered to be one of the players which could take over the role. In an interview after Brisbane's loss to Richmond in round 13, Redden said "it'll be big shoes to fill when Blacky (Simon Black) does leave... but most definitely I would love to take that spot in the team" but yet admits "there's plenty of other boys that have the potential to do that". In the article, Whiting said Redden has a "hunger for the contested footy" and is a "composed young player with strong hands overhead and a great work ethic".
Redden ranked 3rd in the Brisbane best and fairest awards (otherwise known as the Merrett-Murray Medal) in 2011 with 35 votes, finishing only 2.5 votes behind winner Tom Rockliff and half a vote behind runner-up Simon Black. Because of his third-place finish, Redden won the Alistair Lynch trophy.
