From the AFL site....Adelaide is less confident of retaining popular ruckman Ivan Maric, who is tipped to seek greater opportunity at Richmond next year.
Maric, 25, conceded the No.1 ruck spot to ex-Carlton recruit Sam Jacobs this season and was limited to only six appearances with the Crows.
The out-of-contract Victorian's likely departure would be a blow to the Crows, whose ruck stocks have already taken a hit with the retirement of Brad Moran.
There's a short supply of ruckmen in this year's draft talent pool, meaning clubs could look to previously listed players, or the state leagues in search of ready-made big men.
"We've still got Shaun McKernan and [untried ruckman] James Craig, who can play in the ruck, on our list at the moment," Harper said.
"A ruckman wouldn't have been high on our priority list, but if both of those players [Maric and Moran] went it would come up the pecking order."
The Crows, who aren't expected to announce Neil Craig's successor until later this month at the earliest, had planned a quiet trade week, but Harper said the club would become involved if Maric requested a trade to the Tigers.
"If everybody was staying, we probably wouldn't be active but if someone goes we can become involved," he said.
