2 man question, Trail kicks a GT and BI

[roadking]

Good boy JV game, a lot of tall athletic players. I'm lead in a half court set, partner has a goaltending in which everyone in the building including me thinks its a clean block off the glass, I have a good look, play came from my side, ball was on its way up. Partner tweets, hesitates and points as to call GT. He then wants to come to me and talk it over, I tell him as he steps toward me, its your call sell it. Later that half, I'm lead in a half court set, partner misses a obvious BI by the offense.
Question:
Partner had never called at this level of basketball, I know these are judgement calls the trail should have, would you guys of stepped in and corrected the GT and also would you of called the BI from the lead position?
THANKS
