Is it a backcourt violation while inbounding the ball a player leaves his feet in front court catches the ball in the air and land backcourt I say no with no possession out of bounds?

Answer 1

Yes, it is a violation. If you leave the ground from the frontcourt and catch the ball in the air, you establish possession in the frontcourt. Then when you land in the backcourt, it is over-and-back. If you catch the ball straddling the line, however, this is OK.
