Block/Charge/No Call

[hbioteach]

8th Grade Boys

A1 drives from the three point line to just outside the lane and B1 "flops" after minimal contact and A1 misses the shot. I'm the lead on the opposite side. The trail calls nothing. (Has been doing that most of the game so far).

As far as primary area of coverage it is the trail's call.

I'm thinking I should have made a call there:

(A) Block on the defense. 2 shots.

or

By the book:

(B) Technical foul on B1.

What do you think?
Also, how do you handle when you are working with a "weaker" official.
