A whole bunch of people, especially in the national media, have been saying that the Bills are going to take step back by going with Losman this year rather than Bledsoe. They compare it to the situation in Cinncinnati last year where Kitna was benched after a strong Bengals season for Carson Palmer and how they took a step back initially.
I totally disagree that this situation is at all similar. If you look at the Bengals in 2003, they were successful because of their better offense for the most part. Kitna had a pro-bowl type year and was helping to keep the team competitive. So when Palmer started they were going to have a slight step back because it was Palmers first year and the Bengals had been so dependent on their offense.
The Bills this year were not being carried by Bledsoe but by the defense and special teams as everyone has mentioned. Besides a veteran being replaced by a second year player, there is no similarity at all.
