I have to say from reading the article and watching the NCAA champs video that Watson is very smart and composed. First, she's a civil engineering major. Second, she runs in traffic, completely boxed for much of that race, yet it does not seem to faze her one bit. She waits and waits, knowing that a gap will open up, and when it is starting to open up and the Middle Tennessee State runner makes a huge surge and is about to close it down, she darts out at exactly the right moment to block the MTSU runner, without fouling her but with some apparent contact, and to go into the lead. That is a very smart racer, well ahead of her years in race savvy. There are many pros who cannot do that. She has proven this race savvy in winning NCAA as a freshman (how many 800m runners do that? Brazier did it), winning US juniors last year, winning gold at world juniors in the 800m AND the 4x400m in 2016 when she was just 16, and winning world under 18 in 2015 when she was just 15 years old. Do you realize what a splash would have been on the message boards if a U.S. male had done all that in the 1500 or 5000? I'm not sure what's going on with her training right now, but this is a super talent.
The last talent we had with this kind of competition record at an early age was Ajee' Wilson (as a senior, 8 national championships plus world bronze, two world indoor silvers, two world relay golds, in an era with intersex athletes dominating the 800m), who won gold in the under 18 world race in 2011 and gold in the under 20 World champs in 2012.
If you just look at her in the field of that NCAA race, you can tell she is the most talented. I don't know whether this is the right coaching system for her but my bet is that she will not be one of those teen phenoms turned bust, because her competition record last year was just as good as ever.
