Not really over rating Rioli as such but the circumstances and how it occurs
Rioli was extremely happy at Richmond and said as much prior to going up to the gold coast earlier in the year and playing great football.
Things changed when he met Hardwick on the gold coast and we all know what happened and Dimma see's Rioli as an integral part of his plans for GC
Uncontracted Rioli is worth a pick 10-15
Contracted for 3 more years that becomes pick #7 and thats the pick GC have if they had 10 it would be 10 but its #7
Now with GC salary cap issue and if they want 50% salary paid then thats another issue altogether
We have all seen what GC are happy to pay to get $350k-$400k off their books and it was pick #7 just last year
So thats where the over paying comes into the trade
Not sure why you think uncontracted Rioli is worth a pick 10-15 range. He is an okay player but has he even been in the AA squad, much less the AA team?
