Lemme simplify it:
"Takedowns are currently 'worth' too much in MMA. The value of a takedown needs to be scaled down, unless it's a slam. I also hate being smothered by a wrestler and losing decisions because of it."
Sounds about right. My biggest problem with the piece is the author's insistence that takedowns be removed from the effective grappling category. A takedown is offensive grappling: it is used to advance position (standing -> top guard/side mount/NS) which lends then to the next phase, a guard pass/mount/taking the back, and finally going to the submission. Defensive grappling, on the other hand, is used to prevent advancement of position and submissions. If you can stuff a shot, good defensive grappling. If you can stop submissions, good defensive grappling.
In short:
Offensive grappling advances position from standing to a dominant position to set up a submission or maintain control. Defensive grappling is preventing the opponent from advancing in position, defending a submissions attempt, or disrupting the opponent's control enough to regain a neutral/dominant position.
