I find it 100% believable given that the "cripple-things-for-one-teammate-to-sweep strategy" (as Ashenlock put it) is hands down one of the most effective ways to win. The only difference in this from last gen is that switcheroo and trick don't work as well, because the AI is much more likely to switch now. There are still dozens upon dozens of other ways to cripple something without locking it in to one move. While I personally get too bored trying to streak with this strategy, I have absolutely no doubt in T.L.'s run whatsoever. The fact that you called him out for cheating using one of the best strategies in this game mode is a bit ignorant.
