Ok he didn’t shoot “from” the knee, but the second period TD shot came about 1.5 seconds after coming up from the knee.
Plott definitely seemed to be leaning prior to the SV TD, but I did not think he was leaning during the second period TD. Angelo was just too quick for him. Interestingly I believe both his TD’s were from outside singles to Plott’s trail leg, which many coaches would probably advise against.
Overall I don’t really see much difference between a guy in a stance and a guy on a knee. There are certainly ways one could try to attack someone on a knee; or at least maybe try to time your shot for right as he’s coming up. Ferrari also tended to leave the leg that was up kinda far in front, so I think an outside single to that leg could be an option.
But stalling should be based on the action or lack thereof and Ferrari was far more active overall.
