Yardbird, it matters what TM is doing because you are giving the young man advice about his knee, when either 1) you are not teaching these same mechanics you are telling this kid to use or 2) you have a student (TM) who totally disregards your teachings, yet you proclaim him as one of your Marshall students because he may be getting a big contract. So one question is, did you teach him to throw with a "low MTS" score, or did you teach him to throw with all the Marshall tenets and he ignored you? If he ignored you, it says something about what you are teaching. If you taught him to throw this way, then you are a hypocrite. You really shouldn't teach one thing and then tell everyone else they should do something a different way.
Practice what you preach. If it is OK for TM - your student - to do things traditionally (with a low MTS score), then it should be OK for everyone.
And by the way, I can tell enough from the video that TM is not a high score MTS. Even you admit he doesn't score high.
