I think he is just some random guy doing the video check... ...yuck He`s not even cute ....at least not my type.
yes, the ball touching the floor video review is new this time. but i don't think it's the hawk eye technology, that's only for ball in/out. the floor touch/pancake is a visual video replay, it seems.
btw who's that bearded hipster dude that does some of the video review? he's .... yummy.
