REPLY: Just to further clarify---the NF definitions for forward and backward passes are in 2-31-2 and 2-31-5. The NCAA definitions are in 2-19 2a. Note:
- there is a fundamental difference between the way that each code determines whether a pass is forward or backward, and
- in both codes, a pass parallel with the line of scrimmage (accepting each code's differences) is considered a backward pass for rule purposes.
