MSU wrote on The Mat that wrestling from knees is stalling because "in NO way does going to knee allow you to initiate offense" and it's "purely defensive". I and others mentioned that Waters does score frequently from there, and I linked two video instances of Waters taking down top 10 wrestlers from his knees. MSU's argument seemed to shift to how ugly and boring it is, and that Waters "only scores when his opponent comes to him" and "opponents get frustrated and walk into something".
Considering Waters has at least one takedown against just about everyone he's wrestled this year(not named Gilman or Garrett), there must be a bunch of suckers that fall for his "I'm on my knees, come and get me" traps. And for all the flack Waters gets for it, he's usually on his knees only a small fraction of his time in neutral. He beat Joey Dance at All-Star and I'm not sure he wrestled from his knees more than 5 seconds in the whole match. When he does drop to his knee(s), he advances and initiates contact and quickly shifts back and forth from one knee, to two knees, to standing.
To each his own, but you haven't watched many of Waters' matches if you think he drops to his knees to stall. IMO, it's a good defendable position for him that he uses to set up attacks.
