I just turned 40 this year, so I may just be losing my mind. However, it seems to me that several times during a game, a receiver will catch a ball, run out of bounds, and as soon as the ref sets the ball, the clock begins to run. Is this really happening, or am I losing my mind? If it is a new rule, what is the rule because sometimes the clock does not run, such as when a quarterback or a runningback runs out of bounds. Please excuse my ignorance in advance.
