When a coach comes and asks me to "go for help" on a call I have made, the first thing I will say is "Coach, why are you asking me to get help?" If the response is anything like:

"She slid under the tag!"
"The ball beat her to the base!"
"Your partner had a better angle!"
etc, etc...all of these statements are just another way of saying "your call is wrong"
My response is "Coach, it's my call, I made it, let's play."

If the coach comes out with a statement like:

"She dropped the ball"
"She pulled her foot"
Or any other statement that indicates that s/he saw something I may have missed, I will call my partner over and get his/her input.

Of course, after I have talked to my partner, it's up to me to stay with or change my call.
