Jennifer Jones juggernaut still sailing through Sochi opponents after win over Switzerland

With all the talk that Brad Jacobs and the Canadian men were poised to continue their impressive curling roll through the Olympics (and they might yet), a funny thing has happened at Sochi.

Jennifer Jones is "out-Jacobsing" Brad Jacobs.

Serious as serious can be, Jones is in a zone that we've rarely - if ever - seen from her.

Fearless and aggressive, she rarely misses. Now her team sits with a perfect record of 5 and 0 after an 8 - 5 win over Switzerland.

The skipper shone yet again.

Witness her incredible triple in the 6th end. The Swiss had just landed a great one of their own and were looking to get a little something going, trailing 4 - 2. Jones fired that triple take out and then followed it with a perfect freeze with her second, stealing a point and jumping ahead, 5 - 2. Throwing a perfect draw moments after you've just fired a big bomb is one of the hardest things to do in curling, and Jones did it with ease.

"I just have never seen her play as well as what she's playing now," said analyst Joan McCusker. "Full of confidence."

So complete has Jones' domination been so far this week, that when she blew a draw through the house, allowing Switzerland to steal two in the 8th, it seemed more shocking and annoying than concerning.

Jacobs and his boys were installed by many - with good reason - as gold medal favourites at the 2014 games. Jones, meanwhile, was considered a favourite, but with some reservation.

The four-time Scotties winner is rightfully thought of as one of the great women's skips of all-time, certainly when it comes to the Canadian scene.

A spotty international record (her one world championship was earned when the tournament was held in British Columbia) had some wondering (guilty) if she'd rise to an occasion as high as Olympus. If her killer instinct, so prevailing in domestic competitions, would appear at Sochi.

Check and check.

Jones has made a season's worth of terrific shots at this event, almost singlehandedly willing - and shooting - her team to a hairy 9 - 6 win over Eve Muirhead when things started to unspool with the rest of the team late in the game. Against Sweden, Jones chalked up a 100% game. That's a rarity for skips and when it does happen, it's usually because there weren't any really hard shots to make. That wasn't the case when Jones booked her perfect game, however.

In retrospect, the Jones team's roll through the Olympic Trials may not have been given the weight it should have. The same weight Jacobs' perfect run was. Perhaps that's because Jones actually lost a game in that event and there isn't quite the same sheen to a near-perfect record as there is for a flawless one.

Jones is happy, in Sochi, and that happiness was on display during a fifth end break interview. All smiles, it's in direct contrast to some of her previous overseas experiences, when poor ice conditions (like Paisley, Scotland, in 2005) and the like had her feeling blue and losing touch with the field.

There's no such danger of that at the Ice Cube Curling Centre, where there are top-notch facilities and sheets conditioned by well-known and coveted ice maker Hans Wuthrich. As well, getting to Russia well in advance of the competition and with a support team that presented her with an incredible amount of preparatory material.

Here, Jones leads that field and there is just no sense at all that she's about to lose that edge and performance that has her rink at the top of the standings. Whether that translates into a gold medal is yet to be determined, but the Olympic plan continues to unfold almost perfectly.
