Nobody even knows what a legal catch is anymore. A few years ago, there would be a replay and everybody knew if it was a catch. Did he have clean possession? Did he have 2 feet, or an elbow, or a knee down? Then it's a catch.
WHat's a catch now? You got me. You have to have clean possession, then 2 feet, then something else. Nobody exactly knows what that something is. It seems to change game to game.
