Within the span of a week, we heard these comments from clients of ours: 

"I watched a coach (not using CoachDeck) try to gather his team around his phone on the field so they could watch a video of a drill and he was stopping it and starting it and trying to rewind it."

"Yesterday I was heading to practice and I came to a stop light and, while the light was red, pulled four cards out of the deck and had my practice ready before the light turned green."

Which one do you think is best?
