Nope. She is stumped too.
The best the captain can do to explain why more or less the same group of players has suddenly gone up a level is to offer a holistic argument.
"I honestly think it is a bit of everything,'' the midcourter said.
"We did a lot of growing last year. Even though we were losing games ... I think a lot of the girls have learnt from that and now this year when the pressure goes on they are delivering more.
"For us it is just nice that we are stringing the wins together and producing good performances.''
Let's recap, shall we? The Steel has played 12 games, won 11 and drawn one.
It has been a brilliant season and the combined Otago-Southland team leads the competition.
And despite all that talk about how dominant Australian teams were meant to be, the Steel has won all four of its games against its rivals from across the Tasman.
That has to be deeply satisfying, particularly since some voices out of Australia have been dismissive of the New Zealand side of the draw over the years.
There is one major hurdle left, though, and that is the team from Sydney. The Swifts have had a terrific season as well and lead the Australian conference with 10 wins from 12 games.
"Obviously, we've had four good wins against the Australian sides and it does bring confidence within the group. But we know it is going to be a tough challenge this weekend.
"The Swifts are a great side and they are playing some good netball. They are certainly not going to take us lightly so I know we'll have to step up our game this week.''
The Swifts have Silver Ferns midcourt maestro Laura Langman but the Steel has its own lucky charm - coach Noeline Taurua.
Arguably her arrival has been the biggest single factor in the Steel's turnaround. Remember the Steel won just three round-robin games last year, so Taurua has certainly made a difference.
She helped break Australia's grip on the trophy when she led the Magic to the title in 2012. The Magic remains the only New Zealand team to have won the ANZ Championship.
"She just brings a lot of self-belief to the unit,'' Frew said.
"She also has a pretty cool way of looking at the game. She is always looking for new initiatives or new moves and fresh ideas to outsmart the opposition.''
The draw has been very kind to the Steel. Most games have felt like a gradual step up but Saturday's fixture is more of a steep incline.
"You could not ask for a better match-up in terms of preparing for the conference [finals] in a few weeks' time than to finish the round robin with the Swifts.
"It will be a challenge but we're ready.''
