Your statement about 'job performance' strikes me as being an odd statement. Have you ever run a business?(that you owned). I think firing someone for job performance is the #1 thing an employer needs to do IF that employee has been deemed to be performing sub-par. Do you think people deserve a lifetime job or what? I have had 3 businesses in my life and ALWAYS fired people for 'job performance' issues ONLY. That is how people should be judged in my opinion. If Bevell wasn't performing up to expectations, as an employee the owner(GM/coach/etc) or whoever should certainly fire him. We may not agree, but that is part of a business decision. We as fans don't run the NFL teams, so we wouldn't have any idea if Bevell was performing up to expectations.
I have always liked Bevell as a coach and would love to see him as the OC for the Wisconsin Badgers, but I don't think it is unfair to fire him for his job performance at Seattle, if the performance was deemed sub-par. Everyone doesn't work out in every business(same in sports). Those who run the Seattle team made the decision that Bevell wasn't performing up to expectations - that happens in the real world every single day. It might be deemed as unfair by some as how they state it, but that is life.
I don't think you comprehend what Travis was saying. The way coachw12 worded it made it seem like they terminated (killed) Bevell. Hence, the sarcasm in Travis' response to him.
