Illegal pass over the line of scrimmage

[Zeke5]

On a pass play, I'll give the linemen a 2 to 2 1/2 yard leeway downdfield (expanded NZ), but the QB I'll rule tighter. I don't have my rule book, but I'm sure the rule says that the passer has to have both feet in or behind the NZ when he releases the ball. So you may not have an IFP in your case. I'd probably let him slide if he had one foot barely beyond the NZ.
