What can the cats offer that is a fair trade ?
Dangerfield is a restricted free agent. If Adelaide don't match Geelong's offer then the Cats get him for nothing and Adelaide will receive some compo. On the other hand, the Crows can match the offer to force Dangerfield and Geelong into a trade. Geelong then may be forced to offer up two first round picks from 2015 & 2016.
Adel have put match to get decent compo eg via trade
If he goes to the Cats as FA then the compo pick is around 14, Dangefield is worth a helluva lot more than pick 14
Hence, why Adelaide will match (as they should).
Just another example why Free Agency is so flawed
