Question about a fair catch

[Robert Goodman]

The simplest way to put it is that it's illegal for a player who should know the ball is dead to hit. Then it's just a judgment about whether the player should have known the ball was dead. A fair catch signal followed by a catch means the opponents definitely should know the ball is dead. A fair catch signal followed by a recovery...well, then you have to see it as to whether it's a late hit.
