Ryder was elite in 2014, very good in 2015 and is elite now, we got flogged in that deal.
Using the HPN player ranking system PAV, which I think is the current best in the business, Ryder was had PAV ratings of ~21 in those years, which puts him easily in the top 5% players in the game.
Interestingly Hibberd never crossed the elite barrier of the 20, until this year so I think we got reasonable value for him but Melbourne got a great deal as he is now elite.
Melksham has always hovered between above average to very good (13-16 PAV) which surprises me, he also had his second best year (his best being 2013) this year so Melbourne probably win that trade.
Crameri was average until he got the bulldogs in 2015 when he played his best year since his debut year (in which he was ranked in the top 25% of the players). Pretty neutral on this one.
In general, according to the HPN rating system, we got unders on those trades in general.
