1st & 10, at A35. QB takes the snap. Under moderate rush, QB scrambles and advances the ball 2-3 yards beyond LOS/ENZ. Retreats back onto his side of the LOS, almost immediately passes 15 yards downfield to an open receiver who catches the ball and is tackled inbounds. No Offensive Linemen went downfield, etc. (everything else was "textbook clean"). Is this legal?
I argued that this is legal, since the all criteria for a legal forward pass was met at the time of the pass. I am unable to find in the rule book or the case book where a forward pass cannot be made after the ball has crossed the LOS/ENZ, as long as certain criteria are met when the forward pass is made. Others have argued that the right to pass is forfeited once the ball has crossed the LOS/ENZ. Thanks, in advance.
