On what grounds do you say that we paid more for Melksham? Just because we received p29 later you are jumping up and down saying that Ess would have accepted p29. You don't know. They are hard arses to deal with and if we were too we would still be at a standoff with supporters yelling to "do something".
Footy clubs enter each trade period with specific goals to try and secure players they have identified during the season/s eg Melksham, Kennedy and Bugg that will improve their list. The club obviously believed that Melksham was worth a 2nd round pick and Kennedy around a late 2nd to 3rd and they got the job done around those picks.
No one will remember the noise and drama involving these trades in years to come. All we will remember is what great pickups they were.
