Just when you thought the dysfunction couldn't get any worse in Houston ...
J.J. Watt -- arguably the Texans' greatest player EVER -- has just been released by the team ... this after the 3-time NFL Defensive Player of the Year says he asked to be let go.
Watt made the shocking announcement Friday morning ... recording a video explaining the move.
THANK YOU, HOUSTON
"I have sat down with the McNair family and I have asked them for my release and we have mutually agreed to part ways at this time," Watt said.
