We know that a fair catch signal made after a catch has been completed is NOT a fair catch, but it does make the ball dead immediately, and is placed at the spot where the signal is first given.
OK, ponder this one:
Kickoff, A-35. A88 B88 catches the kick at the B-10, then advances to the B-20, where he abruptly stops and makes a waving signal with one arm, but remains standing (ostensibly hoping to get a fair catch ruling and get the ball at the B-25).
Ruling:
--------------------------------------------------------------------------------------------------
Would this still be considered an invalid fair catch signal? Or, is there a point in time or distance at which a signal is no longer considered anything?
Strict reading of the rule would tell us that there is no time/distance limitation for this rule. But, I just wonder about a player that runs 40, 50, 60 yards, then stops and makes a signal? Yeah, a true "what if," but we've seen equally strange things happen.
