Trevor Barker Award winner Seb Ross may have taken his game to another level this season, but he might only be scratching the surface, according to St Kilda Coach Alan Richardson.

The 24-year-old claimed his first best and fairest win earlier this month, capping off a stunning campaign where he emerged as one of the most improved midfielders in the game and earned selection in the All-Australian squad for the first time.

For the second successive season, Ross played all 22 games and thrived on the continuity, averaging 29.9 disposals – the 9^th most in the AFL – 9.8 contested possessions (No. 3 at St Kilda), 5.1 clearances (No. 2), 4.3 tackles and 4.0 inside 50s (No. 2).

After a stellar rise in output from 2015 to 2016 and then from 2016 to 2017, Richardson believes the North Ballarat product still has plenty of improvement left in him before he reaches his peak.

“In many ways, it was a real breakout season for Seb, but he also been building for a few years now. His form this season was no surprise given how hard he works on his game, both physically and mentally," Richardson told saints.com.au.

“Seb’s improvement is a by-product of combining talent with elite preparation. We’re really excited by Seb’s year but probably more excited by where we think Seb will get to as a player.”

Despite having a year to run on his current deal, Ross recommitted to St Kilda for a further three years a fortnight ago, only days after Richardson re-signed until the end of 2020.

Richardson praised Ross’ growth as a leader in his first year inside the Saints’ leadership group, in a year where Jarryn Geary replaced Nick Riewoldt as captain and two other players – Dylan Roberton and Josh Bruce – were included in the group for the first time.

“He has a very good balance between supporting and challenging his teammates, and an ability to make those around him better,” Richardson said.

“With so many experienced leaders leaving the club this year, we’re going to need more players like Seb to continue to develop their leadership.

“I’ve got no doubt Seb will play a key part in the direction of our footy club.”

After overcoming an injury-interrupted start to his career at Linen House Centre, Ross has now played 81 games in red, white and black and looms as an instrumental figure in St Kilda’s pursuit of finals football.
