ADELAIDE and Richmond have struck the second deal in a quiet start to trade week with half-forward Richard Tambling joining the Crows.

The Tigers will receive two NAB AFL Draft selections in return for the 24-year-old; a compensation pick at the end of the first round and a third-round pick, which currently sits at No.50.

The Crows relinquished its compensation for defender Nathan Bock's defection to Gold Coast, with that pick able to be used in any of the next five drafts.

The deal also means Adelaide will bow out of the race for Carlton utility Andrew Walker, who had also expressed interest in joining the club.

Tambling, 24, nominated the Crows as his preferred destination on Wednesday after several meetings with coach Neil Craig.

He played 108 games in six years for the Tigers, but struggled to live up to the expectation that came with his selection at No.4 in the 2004 national draft.

Form and injury limited Tambling to 13 games this season, prompting a mutual decision for him to move on despite having two years to run on his Richmond contract.

Adelaide identified leg speed as a priority heading into the trade and draft period and football manager Phil Harper said Tambling would be a valuable asset.

"Richard needs a change of scenery and our club can provide that ideally for him. We don't have massive expectations. We just see him playing a wing, half-back or midfield role and to just play his role in the team," Harper told afl.com.au.

"He might have been a pick No.4 many years ago, but now he's a pick nothing. He's just a player who we think can play a role at our footy club. The two things that stand out about Richard are his speed and his character.

"We think that from what we've seen of him, he can more than hold down that sort of a role for us and give us that breakaway speed that we've only really got from David Mackay. That burst-away speed adds to our group."

Richmond football manager Craig Cameron said the club was pleased to shore up its position in the draft.

"Gaining a compensation selection will give us great flexibility in the 2010 draft, and in subsequent drafts," Cameron told richmondfc.com.au.

"We set out to improve our position in the 2010 draft, and we believe these selections will place us in a strong position to recruit and develop more young talent through the draft process."

Walker also met with Adelaide officials last week, but will now have to try his luck with the Western Bulldogs or Port Adelaide, which is rumoured to have entered the race for his signature.

Harper said the club was committed to a second trade, but that it wouldn't involve Walker.

"We'll bow out of the race for Andrew Walker now. We've told his management that because obviously we can't do them all," he said.

"We'll just try and focus on what we can do with (Carlton ruckman) Sam Jacobs and try and avoid him going into the pre-season draft."

Jacobs wants to join Adelaide, though Harper described Carlton's demand for a first-round draft pick as "unreasonable".

"Sam won't be re-signing with Carlton," Harper said.

"We've put something to Carlton and we're still talking to them about that. We'll see what happens … we're hoping that common sense prevails in the end."
