ST KILDA remains undecided whether to elevate veteran Adam Schneider or youngster Jack Sinclair from its rookie list to play against the Western Bulldogs on Saturday night. 

Clubs can elevate one rookie mid-year regardless of the number of players on the club's senior list, if it has enough salary cap space to accommodate that player.

With no players on their long-term injury list, the Saints face the unenviable task of making a choice between Schneider or Sinclair. They have both been in good enough form to retain their spot in the senior side.

Schneider has played nine games in 2015, with his leadership skills as important as his statistical contributions, while Sinclair has played 10 games and kicked 11 goals in an excellent debut season. 

The duo kicked three goals between them when the Saints defeated the Bulldogs in round six.

The chosen one will be elevated to the senior list while the other will have to return to the VFL to play with Sandringham.    

A spot may open up later in the season for the demoted rookie if an injury occurs, and the Saints place the injured player on the long-term injury list.

However, they will not be able to select both players in round 13.

The situation has sparked debate about the ongoing viability of the rookie list, with many clubs of the view there should be more flexibility available to clubs to select players on form regardless of their status.

Collingwood list manager Derek Hine told AFL.com.au's Road to the Draft podcast a fortnight ago he would like to see a change. 

"I would like a system where you have an active list and an inactive list, where you are able to move players on and off," Hine said.

"That concept creates competition within your list …  and that would create a lot more scope with what you can do for the list."

Sinclair received a reprieve ahead of the round eight clash against West Coast, with the AFL showing enough flexibility to allow him to play despite his elevation being originally tied to the long-term injury of Sebastian Ross.

Under a strict interpretation, he would have had to return to the VFL once Ross came back, but the AFL determined he was able to fill one of the spots available at that stage because two other Saints were on the long-term injury list.
