From a practical standpoint, I can only find two things that differentiate a kick play that involves a fair catch and one that doesn't:

1. The player signalling for a FC and that doesn't touch the ball is restricted from blocking during that down, and

2. The receiver that signalled for FC still has protection if he muffs the kick and still has an opportunity to complete the catch.

Anything else that I'm forgetting?
