Brisbane captain Tom Rockliff says the Lions failed as a club when they let five first-round draft picks go at the end of 2013.
Jared Polec (Port Adelaide), Elliot Yeo (West Coast), Patrick Karnezis (Collingwood), Billy Longer (St Kilda) and Sam Docherty (Carlton) all asked to leave the club and were traded following the 2013 season.
"Obviously we lost a lot of high draft picks, which is probably our own fault looking back," Rockliff said.
"They all left for different reasons, but if you're a good organisation, a good club, you keep players like that."
