Yes, the basic inbounds situations are generally clear enough because of the concept of team control. But there are those little sticky not so clear ones that just have their specific interpretations that are not readily discernible from the basic four points. You gotta know the specific rule for these situations, because the basic BC violation provisions won't get you there.
1. A1 inbounds to A2 who is FC, ball is thrown toward BC, A2 jumps from FC catches in air, and lands BC.
2. A1 inbounds to A2, A2 catches with one foot foot in FC, other foot in air, second foot then touches BC.
These are the situations to which I was refering
