"Utilizing these standard molecular docking simulations, we obtained an auROC value of roughly 0.5, which basically says you're doing no better than if you were randomly guessing,"
...so just like docking scores for crystal structure derived models then.
To be fair, the authors actually say this:
"These findings show that molecular docking using AlphaFold2-predicted structures is similar to using experimentally determined structures"
...which they then go on to improve through a rescoring model, and get an auROC of about 0.6. Still not great, but better. Again, this is worth doing with experimental structures too.
Basically the MIT press release, and consequently this article, don't really reflect the conclusions of the paper.
