Which is exactly to my point, playing smart...knowing what angle the throw is coming from also how much room there is to the fence matters more for both the catcher and the RF than aimlessly running full speed to impress somebody.
I will have my catchers do it...most of the time when all three catchers are healthy. This past weekend I was down to 1 catcher, due to tournament injuries, in 85° temps with 3 games to go. She wasn't going to trail any runner down the line at that point. As it was, she ended up hurting her foot and later took a foul tip to the groin.
Yeah, she wasn't allowed to trail a runner.
