When did he sign that?Oh I wonder if this is true or not:
"Blucher also confirmed, when asked about the reported clause in Tippett's last contract, that he could be traded to the club of his choice for a second-round draft pick: "There is an understanding between the parties, they would help get him to the club of his choice." But he added, it was also recognised that arrangements had to be "commercial" in the deal."

Adelaide have allowed themselves to be completely bent over if this is the case, and deserve anything they get.
Its unusual but if he was only worth about a 2nd rounder at the time... and if a big part of him signing on was knowing that the Crows would get him where he wants to go if he ever wants to leave... it makes a tiny bit of sense I guess?
