Tremendous talent: Where next for Spirit's MVP star?

Kennedy Kereama believes Izzy Borlase has only shown the world the tip of the iceberg of what she can do.

The Bendigo Spirit suffered a season-ending 81-75 defeat to the Perth Lynx in game two of their semi-final series on Tuesday night, but the coach paid tribute to the impact the competition's MVP has had on his side.

After a campaign affected by the loss of stars Marianna Tolo (pregnancy) and Casey Samuels (foot) for large chunks of the season, Borlase has stepped up, becoming the league's youngest MVP in 15 years and averaging the most points per game in the competition (22.8).

On Tuesday night, she dazzled again, falling just short of a triple-double with 23 points, eight rebounds and eight assists.

But Kereama believes she has much more to show.

"The scary thing is, you are just seeing the tip of the iceberg. This young lady could do anything," he said.

"To have someone like that within our program has just given us a tremendous amount of challenge to continue to try and provide the resources needed for her to continue to grow and develop.

"It's been a fun ride working with Izzy. She's a tremendous talent."

Borlase's contract is up at the end of this WNBL season, and with the MVP award under her belt it gives her an excellent platform to push for a WNBA spot.

Although she could return to the Australian competition as it falls in the American league's offseason, current stalled collective bargaining agreement negotiations point to the WNBA being postponed and impacting the start of the WNBL season.

With the future in limbo, Spirit captain Kelsey Griffin believes the WNBL needs to keep the 21-year-old, insisting she must be the face of the league.

The 38-year-old added Borlase has grown significantly since moving from the Adelaide Lightning in the offseason.

"We had 10,000 preseason games all across Victoria, and I was imploring Izzy to get outside herself. But she'd been really quiet," Griffin said.

"Before the game (on Tuesday), she came up to me and said, ' You always give me a pep talk, but I'm going to give you a pep talk today.'

"For Izzy to go from being someone who was so inside herself to then being someone who's coming up to a 38-year-old who's played 250 games ... that's the thing I'm most proud of."

Griffin said she doesn't know if the semi-final loss was her last game, with the five-time championship winner and 2019 MVP adding she has a "difficult decision" ahead of her.

The 38-year-old's contract isn't the only one now expired with Tolo and young guns Olivia Pollerd and Meg McConnell also finished.
