Improved Drill - Ex. #1 (Puck Focus)

In a nice, short piece (if somewhat low quality) made for Vaughn Hockey, goalie coach Jon Elkin demonstrates two better versions of a simple low-shot rebound drill with a single goalie. First, there is a single live puck at all times, allowing rebound focus and better game simulation. Second, when there is no shooter to whack in rebounds, the goalie tracks the rebound as if he expects a second shot; when there is a second shooter, the goalie is in effect 'rewarded' with a lower-quality scoring chance based on how well he controls the rebound.
Note that what Elkin calls the "power leg" at the start of the clip is simply his term for the backside leg.
The one very clear issue in this video is that the goalie gets no elevation on his rebounds, even though all the shots are on the ice, and he gets his well-disciplined stick on all of them. His stick should be ramping those pucks to the back glass, so that only a shooter with incredible hands and a lacrosse background could have a prayer of putting them straight in. (It is possible, however, that Elkin actually instructed his student not to do this in order to demonstrate the drill, in which case the goalie is to be commended for his stick skills.)
Note that this would not qualify as 'visual attachment waste,' since the entire point of the drill is visual attachment and tracking the rebound. Waste occurs when every single puck in a team practise - where the goalie is *not the only player on the ice - is overzealously pursued. See video reply for more...
