The NCAA, infamously slow to adopt the technology used in the NFL for coaches to relay plays to players, passed a resolution over the summer that will allow the use of comms during non-College Football Playoff bowl games. As of last week, The Athletic reported those same games will also allow video review via tablets on the sidelines.​
