I don't have audio capability at work, but it appears the official is calling a pushing foul on blue #40. So, the ref in the video apparently thought the screen was legal and blue #40 was trying to push through...is this interpretation of the clip correct?
From the perspective of the camera, the screen looked clean and the contact looked incidental. I'd like to think I would "no-call" this, but I would be more inclined to understand a blocking call on gold #14. IF the foul call was on blue...then I guess gold really sold it!
