So how do you go about this? How do you measure eight seasons of sustained excellence against 10 games of eye-opening superiority?

How do you measure the past against the present?

How does Alain Vigneault handle the situation in the Rangers goal without creating the type of controversy the coach left behind in Vancouver?

Henrik Lundqvist has the track record, not to mention the contract (but we just did, because it’s an inescapable part of the equation), and we all recognize that.

We all understand and appreciate what he has meant to the Blueshirts from the moment he arrived from Sweden in September 2005. Team MVP seven years running, a Vezina finalist five times and winner once as voted by NHL general managers.

But Lundqvist has struggled nearly all season in winning only 10 of his 27 starts with a sub-standard 2.77 goals-against average and .905 save percentage that ranks near the bottom of the league.

And as he has faltered, the Rangers have faltered in front of him, playing careless and often nervous hockey.

It’s as if both he and his teammates have been waiting for something bad to happen. It usually has. Ten wins in 27 starts.

Seventeen losses, not including his aura.

Into the breach, backup Cam Talbot, who has won eight of his 10 starts following Monday’s 2-1 shootout victory over the Maple Leafs at the Garden, 24 hours after the 26-year-old NHL freshman’s 4-1 victory over Minnesota.

The Rangers have played their best hockey in front of Talbot, who exudes confidence while playing big in net. If there’s a distinct style, it’s an economical one, and no, that is not a reference to the contract under which he will earn $562,500 per through next season.
