I've read some reviews of this book (not at Good Reads), and the thing that people seem to miss out on is that Jake should be associated with the steers in the story. He is in a pen with the wild bulls, but like the steers, he is sterile because of his war wound. Also, like the steers, his job in the story is to round them up and calm them down, like when the bulls are first delivered off the train. One of the steers get gored in the pen, just like Jake gets knocked out by Cohn. I don't understand how that gets missed in everyone's analysis of the text.
