If it had been closer, and scooped up, the red flag may have come out, but the ball was left all alone by the defender...poor choice on his part.

You can't challenge a "no-fumble" call if the whistle has blown.

You are right, but somehow that ruling seems like it needs to be changed. I don't know how, but that was a fumble. The receiver even took a step and a half to progress after the "catch" before he was smacked.
