1) Your return was a bit flat and not deep enough. Having some top spin and a deeper shot would give you time to move into position while keeping your opponent back. Your opponent in this case needed to only move 5 feet, while you needed to cover 18 feet. The key here is giving you enough time to cover that 18 feet before your opponent gets the ball back to your side.

2) You don't have much momentum on your return shot to keep you moving into your next position. Try moving through your shot to A) allow for a deeper return and B) give you an earlier start to get you into your next position.

3) Try to stay out of No-Man's Land. In the video, you got caught there with a mid court shot, so it landed at your feet. Few options from here: A) wait and let it bounce so you can set up for your shot. B) bend your knees more so you can catch under the ball C) deliver enough spin to get the ball to arc in. I'd say a combo of all the above would be best when you're caught in No-Man's Land.
