1st play - I got nothing. The 12th man left prior to the huddle being broken.

2nd play - At first I thought flag, but after thinking on this a little more I have changed my mind. You have a clumsy kid who tripped and had illegal contact that did not affect the play. I have nothing. On the other hand, if B1 had could reasonably impacted the play, I would then flag. This comes down to judgement and I would apply the same logic as applied to pass interferance on the opposite side of the field.
