"The catch rule, proposed by the league's competition committee at the behest of commissioner Roger Goodell, will eliminate the requirement to maintain control of the ball throughout the process of going to the ground. Instead, it will define a catch with a simpler three-step process: A receiver must control the ball, establish himself in bounds and perform a football move such as taking a third step or lunging with the ball in hand."
