I could tell it was a high stick from the far end of the arena. The shot was headed over then net, suddenly it's in. Easy call, IMO. Not sure why they had to replay it, but there was a lot of traffic in front.
Hats off to the Mariucci arena "dj" for playing "Another one bites the dust" while Greer lies crumpled in the corner, with the trainer sprinting out to him after getting crushed from behind. Way to promote sportsmanship.
