THERE's a good reason why Sam Colquhoun was largely missing in action at last week's NAB AFL Draft Combine.

During one of the most important weeks of his football life, Colquhoun understandably had more pressing things on his mind.

On Sunday afternoon, the South Australian teenager will line up for Central Districts in the SANFL reserves Grand Final at AAMI Stadium.

All eyes will be on the 17-year-old in the SANFL decider, much like they will be in November's NAB AFL Draft.

Colquhoun is considered a likely top 20 pick, but the talented youngster told AFL.com.au he just hoped a club would pick him up.

"I've got no expectations, just hoping for an opportunity," Colquhoun said.

As a junior, Colquhoun represented South Australia in cricket at under-15 and under-17 level.

But his focus is now firmly fixed on football this week, and in to the future.

While he was a notable absentee for much of the combine, Colquhoun flew in to Melbourne on Thursday and was interviewed by a number of AFL clubs.

"We didn't quite get to see the best of him test out here, but I'm sure there'll be plenty of eyes on him Sunday, that's for sure," AFL Academies Development Manager Michael Ablett told AFL.com.au.

Those same eyes would have marvelled at his consistent performances for South Australia right throughout the NAB AFL Under-18 Championships earlier in the year.

So much so, the rebounding defender was adjudged his state's MVP and earned All-Australian under-18 honours.

"He had a super championships and was probably the most consistent performer out of everyone in the five games," Ablett said.

Colquhoun was damaging off half-back, averaging 28.4 disposals and six marks for the carnival.

His overlap run was piercing and his unflappable nature engineered much confidence in South Australian teammates.

South Australian under-18 coach Brenton Phillips said Colquhoun has a rare sense of knowing, at all times, where the football is heading.

"His ability to be one and two steps in front of the contest and read it and get to the next play is quite amazing," Phillips told AFL.com.au.

Ablett agrees, saying Colquhoun is an outstanding talent with the necessary football nous.

"He's a little from the old school. He's grown up with a fantastic knowledge of the game and his ability to read it; that's why he finds it so well," Ablett said.

Central Districts is renowned for its one-on-one brand of football, but Phillips rang Colquhoun's reserves coach before the under-18 championships with the specific role for him to be the "drop off" player.

Importantly, Phillips said Colquhoun has successfully reverted back to the Bulldogs' accountable style of football during the SANFL finals series.

But it is his attacking flair and a knack of thinking through different scenarios on the football field that will appeal to prospective AFL clubs.

"You sort of always look at the guy who gets the most football at championship level and he's the one," Phillips said.

Colquhoun admits even he exceeded his own expectations during the season.

"My goal at the start of the year was to play state footy and senior footy at Centrals," he said.

And while he didn't manage a senior game for Centrals, you get the feeling a reserves premiership on Sunday and being drafted in November will make up for all of that.
