No clear look on fast break...

[zeedonk]

I'm looking for advice on the following situation at different levels of play (MS, Sub V and V):

For 2 person, I am trail and team B steals the ball and heads the other way on a fast break. A1 defends B1 going to the rack. I am not to the end line and am preparing to find an angle to see the play and officiate any contact, but A1 is between me and B1. I may be straight-lined or not, but in any event, I don't get a clear look and B1 goes up awkwardly or in general looks like he's fouled. I don't see obvious contact, but can't be sure either way.

How best to call this play? I know that it's not appropriate to call what you don't see, but I also recognize that there are game management situations that may call for something. At the lower levels, I'm OK with managing this. At the big boy level, calling or not calling will lead to lots of discussion with the Head Coach.

Whaddya got and how do you discuss it with the coaches?

In 3 person, I am hoping that the C comes in to help me, but the same question can be asked there too.

Thanks for the sage advice...
