what's up with Div. 1 umps

[ggk]

i've recently adopted the "2 steps fair" for plays at first. you get a great look at the possible pulled foot from this angle. this is my first year doing college ball and i had play where F3 had to stretch for a throw and clearly came off the bag. i called the runner safe and sold it by indicating that F3 was off the bag. defensive coach went ballistic and demanded that i get help. i refused to do so for the reasons that have been previously stated. i had a great look at the play from 15-20 ft away. there was no way i could go to my partner for help on that play.
i know "get it right" is the mantra and i'm all for that, but is there any ncaa policy which requires us to confer on such a play just to keep a coach happy? i considered going to my partner and telling him that i have the call, but i just want to placate the coach - but i chose to stick it out and take the heat. the only downside for doing so is that you look stubborn and bullheaded in the eyes of the coach. is pride worth creating such an impression?
