BBW or not ?

The responses are along the lines I was thinking. I would say if it is clear that the FB is a blocker (this would be even more true on a sweep play once he's outside) and he gets taken out in the legs, then a flag on the defense in this situation is warranted. I would believe the farther to the outside the play happens the more apparent it is that the FB is a blocker and not a runner.
I also believe that the defense must be given full latitude to believe that the FB is a runner first and blocker second.
