The NFL is not football.

[Piglet]

Well sure, it would be great to have a receiver who can see over the field, but it doesn't always work that way tho. He's got to be able to catch the ball first & foremost. 

Would it not be better to have a 6ft 6in receiver that is able to catch a ball.?  Let me explain.  Height is an advantage.   The higher the hands can go, the chance of a catch increases, especially if the defender is not as tall.

There, ive revolutionised your football in a moment.

And yes, it does always work that way.
