Better way to evaluate goalie performance

Former NHL goalie Steve Valiquette, who does game analysis on MSG, has identified what he believes is the most important line on the ice, the line he believes solves the elusive measurability of shot quality.

It's a line down the center of the ice, starting from the top of the circles and extending to the goalie that cuts the offensive zone in half. Valiquette calls it the Royal Road, a term you MSG viewers might have heard, and he believes tracking goals using that line as a compass can change everything.

He's tracking every goal in the NHL this season and compiling statistics for each goaltender in an effort to provide a true evaluation of their performance.
