Shotput-This event seems like beta testing for all the cooler things that could be thrown: a spear (AKA the javelin), a giant yoyo (AKA the hammer throw), and a Frisbee (AKA the discus). In this event, it looks like the thrower is deriving his throwing power from getting a hickey from a bowling ball. Yuck!
Solutions:  If we absolutely need a 4th throwing event, you can’t go wrong with axes considering people actually pay money axe throwing.  Easy sponsorship money.
