I can not understand why the pro players yell "come on" after a good shot they make. Seems to me, I'd yell it after a stupid shot, to tell myself to get with it. I'm not sure why I'd tell myself "come on" after a good shot though. Why are they telling themselves this? Seems like they could come up with a better phrase if they are trying to encourage themselves. Any ideas why this phrase is deemed to be something to yell after a good shot?
