His push to get Palmieri away was unnecessary since Palmieri had already exited the crease. Had he not done that, he would have had ample time to get set and react, as evidenced by the fact that despite the "interference" he was still able to track the puck to the point where he slid and was in perfect position to make a save before Palmieri deflected it against the grain.
Really the only argument is if you believe he HAD to retaliate by pushing Palmieri since when he made the decision to push him he hadn't yet exited the crease and he had been bumped by him.
I don't believe he did have to, therefore he would have had time to be set for the shot as evidenced by the fact that he very nearly was regardless.
This is how finely you’re chopping the sequence to get to a non-GI conclusion:
(seconds on the clock)
Point of reference: 11.2-10.4 - Defender walks the blue line with the puck, continually changing the potential location of the shot until release
Meanwhile…
11.1 - Skate-to-skate contact, knocking both players off balance
10.7 - Body contact along Elvis’ leg, blocker, shoulder
10.5 - Push-off with the blocker slides Palmieri out of the blue paint, ending body contact
10.4 - Approximate release point of the shot
10.4-10.2 - Shove with the glove hand
9.9 - Shot tipped
9.8 - Puck passes the goaltender
9.7 - puck in net
That is all easily verifiable by watching the overhead angle with clock overlay.
So you’re saying that Elvis had 0.1 seconds, from the end of body contact until the initiation of his push-off as the shot was on its way toward him, to decide that he didn’t need to push off a second time.
And from the time of that decision, he had 0.7 seconds to completely recover from the effects of contact, reading the incoming shot and deflection, and physically get himself in position to play it correctly (which at a minimum would have involved pushing past the crease to cut the angle).
So having given him 0.1 seconds after being jostled to re-read the play, and 0.7 seconds to physically adjust for a shot that was already in the air, your conclusion is that the contact was not a factor.
Am I getting any of that wrong?
