If inexperience played a factor in West Coast's demise at the hands of Hawthorn on grand final day last season, the Eagles have done much to address the issue long before the ball is even bounced in 2016.

As AFL teams go about their pre-season work with in some cases dramatically different-looking senior lists, it's West Coast whose age and experience profiles have shifted most significantly ahead of the new season.

In 2015, the Eagles' list ranked 11th in the AFL for age and only 10th for amount of games played. But despite the loss of some experienced hands, such as Matt Rosa and Scott Selwood, West Coast will still head into the new year with the fourth-most experienced list in the competition and the sixth oldest.

The Eagles picked up three seasoned AFL players in trading in Lewis Jetta, Jack Redden and Jonathan Giles. At the same time, several rivals have lost more experience and gone significantly younger.
