My take is that not one of them actually saw it. Here's the way I see that discussion playing out:
U2: Did you see it hit the runner??
U3: Nope. Lets ask the other guys. HEY GUYS COME HERE.....
U2: Did either of you see it hit the runner?
U1: Nope. I was moving to get the play at first.
HP: Nope. I woulda called it if I saw it.
U2: Well, the ball went 3 feet wide of the shortstop who was poised to make a play.
U1: And the entire defense just ran to the dugout as soon as it happened.
HP: So everybody in the place thinks the ball hit him except us.
U2: Yep. And the team on offense is up 6 runs in the ninth inning.
U3: And the team on defense in the home team.
HP: So if we don't make the call these fans may go ballistic.
U1: And if we do make the call, the offensive team probably won't argue all that much.
U2: Can we legally correct the call?
HP: Who cares. The call won't effect the outcome of the game and I wanna get out of here alive.
U2 (leaving the huddle): OOOOOOUUUUUUUUTTTTTTT !!!!!!
