Goaltenders don't "catch" the puck with their pads. That's not even a thing. Especially when you are reacting at point blank range.
As hard as it might be to believe, defense plays a big role in how good your goalie plays, either by disrupting the play, limiting the window for the shooter, not leaving shooters alone opposite the play, and clearing out rebounds. What exactly is the role of the Sabres defense other than irony?
