Those of us who have been long-time football fans recallyears ago seeing coaching staff treading the sidelines holding clipboards with sheets of paper flapping in the breeze. As players came back to the bench, the coaches would scribble out plays or flip through play sheets to diagnose what just happened out on the field.
Things have moved along. Now, the TV camera picks up the players huddled around their blue Microsoft tablets. For the minute or two they have on the bench, the team is watching video of the last play to figure out what to do better, isolating a weakness of the opponent, or figuring out how to keep on doing what just worked.
