"Brodie [Murdoch] had an interrupted pre-season and didn't really get going until the season proper started in regards to his continuity of training," Alan Richardson told SAINTS.com.au on Thursday."He's been building for the last month and his last few weeks have been really positive. He's running where we need him to run, his attack on the footy has been strong."

2013 REVIEW: Brodie Murdoch

And while a large part of Murdoch's appeal is his adaptability and flexibility, the first-year coach expects the 20-year-old from Glenelg to spend the majority of his time in defence."He has some real flexibility in his game but we are probably going to need him more down back than through the middle of the field or even forward for that matter - because he can play multiple positions. He'll be an important part of our back six."Ross, who has been selected in the midfield, has been nothing short of superb for Sandringham this season, and after 16 AFL games, is seemingly poised to make a consistent impact at the elite level.

"Seb's form has been great," Sandringham Zebras coach Simon McPhee said in his VFL mid-season review last week."He's spreading hard, he's winning contests and he's getting plenty of the ball. So we are pleased with how he is going."The No.25 selection in the 2011 National Draft has averaged 26.8 disposals, 6.2 clearances and over a goal per game for Sandy in 2014, following on from 13 senior appearances last year in which he averaged 15 touches per outing.Tom Simpkin, Sam Dunell and Josh Saunders have been named as emergencies, while David Armitage will play in Sandringham's VFL 'scratch match' against the Casey Scorpions at Trevor Barker Beach Oval on Friday, 2pm start.
