I'm not sure about all that stuff you said there as I tend to take a break from the board for the most part during the quiet summer months, but I don't think that clip necessarily demonstrated particularly good lateral movement, I'd say it more demonstrated good anticipation of the play, the tremendous reach he has with his condor like wingspan, and a good glove hand. From what I've seen of his lateral agility in being able to push off and cover distance, I'm pretty sure more than a few NHL goalies would completely smoke him if they were just drilling specifically lateral agility, but ultimately it's just about stopping the puck and he used the tools he had to do that in spectacular fashion on what was a very tough save to make.
