GETTING confused as the brother of Port Adelaide star Robbie Gray doesn't bother namesake Sam Gray one bit.

"lt's always a bit of a laugh because I usually get asked once or twice a week," Sam told AFL.com.au.

"I've told people before that we're not, but they keep thinking that we are.

"I just go along with it. It's a real compliment.

"Robbie's one of the best players in the AFL, so if people think I move like him, I'm going to take it."

Both Grays – who are unrelated – will line-up for the Power when they host West Coast at Adelaide Oval on Saturday.

Robbie's ability to hit the scoreboard has been a major weapon for the Power, but Sam has also made an impact in a new role in attack this year.

The midfielder has been used as a small forward with an emphasis on applying pressure inside the forward 50.

"I spoke to Ken (coach Ken Hinkley) before the pre-season and he said 'we're going to throw you up forward, and hopefully you can run up and down the ground and put some pressure on for us'," Sam said.

"I'm really enjoying that.

"It's going from the mindset that I need to get 25 or 30 touches each week, to making my 10 to 15 touches really positive and getting six tackles a game, or inside 50 tackles, which are really important for us.

"It's more about the pressure acts and the chase downs, that's what we're looking at.

"The goals are a bonus."

Gray's job is to allow key forwards Charlie Dixon and Jackson Trengove to be the focal targets in attack.

"Both those big fellas are really important for us because when they don't mark it they always bring it to ground for us smalls to crumb," he said.

"They're also getting on the end of a few goals as well, which always helps."
