As I read it, your only change to Mick sitch in your first case is that the ball comes back to the f/c before blue touches. This is irrelevant. Blue cannot be first to touch after it has gone b/c, regardless of it's current position. Think of the case where white never touches, blue attempts to save it from going b/c, blue's save attempt bounces b/c then goes f/c. It is the equivalent to your case, and it is a b/c violation.

Your second situation is not a violation because the inbounding team never had team control in the b/c. The fact that it returned to the f/c is irrelevant in this case. Pass receiver can be f/c, have ball bounce off body, hands, etc., (as long as there is no player control established on the touch), ball go b/c, and receiver or teammate retrieve the ball from the b/c. No violation.

so you had it right in this case, but for the wrong reason.
