Played 20 games in both 2016 and 2017. Parish increased his PAV (hpnfooty.com) score from 9.13 to 11.34, with a fairly even increase in all three areas (def, off, and mid). He was according to PAV, the slightest of margins less valuable for us than Watson, and our 11th most valuable contributor overall.
I like the Parker comparison, who had a PAV score of 7.98 in his second year. Parker, however hit his stride massively in his 3rd (~15 PAV) and 4th seasons (bonafide elite with a PAV of >20)
Parish is tracking beautifully, but the third season is where we can expect to see the real benefits of the AFL program to start paying dividends. Personally, I think it is his development more than any other single player that will influence our rise up the ladder in 2018.
