Bonking on the head the theory that "Richmond give up big points to midfielders". Perhaps they did in the past. Below I have collected data from all the significant performances from opposition midfielders in 2021, either in terms of disposals or SC points.

While I fully expect Macrae to get 40 disposals and 145 points tonight, this is enough evidence for me to go Grundy into Gawn, rather than Macrae into Grundy. Grundy could go 160+ against a ruckless GCS.
