COREY Enright's positive influence on his developing teammates is something for Geelong to consider when making a decision about his playing future, coach Chris Scott says.

Enright is set to become just the third Cat to reach the 300-game landmark on Sunday against Melbourne, joining Ian Nankervis (325) and John 'Sam' Newman in the exclusive club.

Midway through his 15th season, the triple-premiership defender remains as consistent as ever, with Enright reeling in a career-high 14 intercept possessions in a best-on-ground display in the Cats' 23-point win over Port Adelaide last Friday night.

But Scott said the popular backman's value to the regenerating Cats extended beyond his own form, with Enright's influence around the club set to be a key factor in discussions about him playing on in 2016.

"We have talked about it (him playing on), but really the situation at the moment is that we've both agreed to keep an open mind – when I say both of us I mean 'Boris' and the football club," Scott said.

"There's a lot more to consider than just how the individual performs in their last year or two as well.

"The influence 'Boris' has over our group as a whole and the way he's adapted to the changes in our game over the past five or six years have meant that his contribution to the development of our young players has been massive."

Enright, who turns 34 in September, said this week he wasn't worrying about his playing future, and is instead focusing on enjoying his football and teaching the Cats' youngsters.

Scott was certain the much-loved defender would have the club's best interests at heart when he decides to play on or hang up the boots.

"We haven't sensed for one moment 'Boris' thinking about himself or living in the past, he's keen to move forward," Scott said.

"I think when we discuss Boris' future we're always best to defer to him, because it's a pretty safe bet that he'll do what's right for the club."
