Lead call over the back foul(pushing)

[PIAA REF]

I like when C can get the pushes on rebounds. I go over that in my pregame with whoever I am working with. And with my playoff crew we seldom have a push on a rebound called by the lead. That being said, I don't think it is wrong for lead to call it. If C passes or misses and it needs to be called then by all means go a head lead and call it.
One example that I really see is a rebound going the the short corner on leads side. This probably would be seen best by lead. (Unless Trail closes down).
