The gist of the idea, as described by Judd Zulgad on 1500 ESPN, is that you bring Alex Stalock off the Minnesota Wild bench for over-time periods, even if Devan Dubnyk has started and held the team in the game until that point.
It’s bold though, given teams typically view a backup goalie as just that. They don’t normally see ice-time unless it’s a lesser opponent, the second of two back-to-back games or if the starter is performing poorly enough to be pulled.
To institute such a bold shift in thinking, you need a coaching staff that is willing to adapt and adjust with the times.
