In watching the replay many times on my crappy extended play VHS tape, that's what I saw, too. However, it should be pointed out that one of the ARs was in position to see everything. I would hope that he informed Adam about what he saw leading up to the hit.
The other thing I saw that made me curious is that it appears that a Sioux player (Marvin?) got his stick on the puck in the corner and shot it up the boards where Bina was waiting to touch it. Could it be that Bina saw the Sioux player gain control and that he expected a whistle before the puck reached him? Perhaps that's why he was so totally unprepared for Paukovich's hit.
I think Hakstol came of age as a head coach at that moment.
