Forget about the gruelling running sessions, West Coast players will start heading to the all-you-can-eat buffets as coach Adam Simpson attempts to transform his side into a premiership contender.

The Eagles finished ninth in Simpson's first year in charge, with Richmond's upset win over Sydney on Saturday robbing West Coast of a dream finals berth.

Simpson said his team deserved to fall short of finals football given they failed to beat a single top-eight side all year.

The former North Melbourne star believes a bigger midfield outfit will help transform West Coast's fortunes in 2015.
