Hartman: NFL approves much-needed changes to catch rule

A player who makes a catch may advance the ball. A forward pass is complete (by the offense) or intercepted (by the defense) in the field of play, at the sideline, or in the end zone if a player, who is inbounds: 

(a) secures control of the ball in his hands or arms, prior to the ball touching the ground; and  

(b) touches the ground inbounds with both feet or with any part of his body other than his hands; and 

(c) maintains control of the ball after (a) and (b) have been fulfilled, performs any act common to the game (e.g., tuck the ball away, extend it towards or over the goal line or the line to gain, take an additional step, turn upfield, or avoid or ward off an opponent), or he maintains control of the ball long enough to do so.
