Former quarterback Kurt Warner discussed the possibility that Brett Favre could lose his job to Tarvaris Jackson for performance issues. ?In a normal situation, I would say, ?No way,? with Favre, but I think there are a couple of factors,? Warner said. ?First you see coach (Brad) Childress and the relationship, and you start wondering if something is deteriorating there. Favre has not played that well this year. Now Jackson comes in and you win. You see the trend all around the league. Who gives us the best chance to win? ? ?If somebody is winning, you stick with that. I don?t think it?s out of the realm of possibility if this happens, and Jackson plays well, that he becomes the starting quarterback, at least for a while, if he can show that he can be successful with this football team.?
