I think Parish is currently Essendon's best ball winner and so trading him would set the team build back a long way. Hobbs, Caldwell, Perkins, Durham, Tsatas etc are all very young, Merrett is really an outside mid given his lack of size and others like Shiel, Setterfield and Stringer are too injury prone to stay on the park. He obviously has deficiencies with his ball use and ability to run defensively. I would prefer to keep if possible but if he is asking for an outrageous deal it sets a poor standard for the rest of the team knowing he could get the big money yet not do team oriented things defensively
