Martin Biron has played in 44 games in the past three seasons.
By comparison, Henrik Lundqvist, between the regular season and playoffs last year, played in 55.
It's not Biron's fault. He's playing behind an all-world goalie. It would be a bad thing if he played a lot.
Still, now that we're back to a full schedule, Biron will have to play more. Lundqvist will need rest, especially with the Olympics, where he will play a lot of minutes for Sweden.
Biron is a fine goalie, but there has to be a real concern about rust. He can get all the practice time he wants, but there is no substitute for game action. Forty-four games over three years is simply not enough.
If Biron has to play for any extended period of time, the Rangers are in trouble. But even if he plays in 20 games, it would not be surprising if he struggles, and if the Rangers look to upgrade the position.
