Re: What does Keenum have to do to convince you he's the guy going forward?
Unless Keenum comes in and throws for a jillion yards and TDs, you probably won't know if he's starter material after just one game anyway. And if he does come in, he'll be running Kubiaks ultra-conservative game plan. So if Keenum does come in, he just needs to NOT make mistakes and NOT continually throw behind the receivers.
The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom.
