To be fair, not many goals when in a blocking Bfly go through you.
As well, with Weber's shot, and a lot of NHL calibre shots, reactions times are slim to none. It's why positioning is the largest factor in playing goal.
I haven't seen the play, nor the save, so I may just be talking nonsense here, but the difference for Lu to come out an extra 6"-12" and block a significant larger portion of the net over getting a half second extra reactions time (exaggeration), the safer move is taking away the net.
You should probably watch the save before you comment, it was really unorthodox and not just an extra bit out of the crease. (Not meaning to sound *****y). He charged out and really put himself out of position. He made a great desperation save but even he was shaking his head afterwards.
I thought Kassian showed some really great flashes of brilliance this game. He does have some lapses still for sure on those drop passes and in his zone but he made a few great moves- his power move out of the corner, and his deke through the dmans stick. Some very Slick hands. Nice to see and definitely not run of the mill 4th liner material.
