Post Play

[Ref-X]

Hello all,
I would like to get some feedback from you guys.
I was working a JV boys game and there where a couple of big kids on both teams. After the game a long time Varsity official was talking to me about officiating and he noticed me coming ball side on plays in the post. He told me he never comes ball side, and that there was no reason to. For two reasons,
1: "what more do I need to see by coming ball-side that I canÂ’t see from where I was". 2: "if I trust my partner I will never need to come over". Now this goes against every thing I learned about officiating the post. So I wanted to know how you guys officiate post play. Do you come ball-side?? Thanks
