Goddard ain't no elite midfielder. Does he rank alongside Watson, Selwood, Pendles, Mitchell, Cotchin, Swan, Murphy & Co. You could argue successfully that the likes of Kennedy, Jack, Sewell, Stanton, & Swallow are all better.
Therefore the coin he's on is way overs. About $500,000 would be about right.
Essendon's midfield was thin so they were willing to pay the extra. All clubs have done that at some stage, but let's not pretend he's in the top bracket of on-ballers.
(Didn't mention Ablett because he's on another level)
But Goddard is not a true midfielder. He is a utility similar to what Hird used to be. They can play anywhere bar ruck. Goddard is probably more valuable than the elite midfielders due to his versatility.
