Don't waste your time with Byers. He's been at this for years. He won't produce any meaningful data and won't produce any testable hypotheses.
Its pretty simple. He says that it all happened in a single flood event but won't produce any scientific evidence for such an event because he's afraid that real scientists will challenge him.
Everything is: They COULD have been buried in a flash flood. They COULD have been sorted out due to the turbulent waters. They COULD have scavanged and slowly picked eachother apart while fighting to swim and stay alive during a falsh flood in the midst such turbulent waters capable of sorting geologic strata churned underneath them.
