That's the operative language. If you've got an elitist attitude and a selfish personality, well, you've gotta have the goods on game day. Jim Kelly was cocky son-of-a-B word, but he had all-world talent and earned it. Losman/Grossman, um, less so. That language basically means the same as this, from earlier:
If it works, you're a swaggering winner. If it doesn't you're a 'hole. Couldn't tell you which he's going to do.
