The problem with your semi-analysis is that you're assuming they're supposed to be immediately "better." I'm not really the right person to defend Marv and Co. as I wasn't happy with Marv's hiring to begin with and wasn't thrilled with the draft. That being said I'm still willing to give the new regime some time to show improvement.
You, on the other hand, seem to have an agenda. You made up your mind awhile ago that you didn't like the direction of the team and are looking for any and every opportunity to say, "SEE, I WAS RIGHT!" The problem is you're not right, you just think you are. You might end up being correct but it's far too early to jump to that conclusion yet.
I'm sure you don't want to hear it but when a team installs a new O and new D schemes, loses their primary receiving threat on O, shuffles the OL and has 4 rookies who are either starting or playing significant amounts of time on D you're bound to go through some growing pains. This would be true even if the team was heading in the right direction.
I'm not going to claim that the team is heading in the right direction but I'm not going to claim the opposite either, it's just too early to tell. People who want immediate results have unrealistic expectations. I'm as tired as any Bills fan of losing but you can't blame the current GM or coaching staff for that. They need to be given the opportunity to do their jobs.
In addition to the growing pains check out the schedule. The combine winning percentage of the teams the Bills played in the first 9 games last year was .423. That's a pretty easy schedule. The combine winning percentage of the first nine games this year is .580. That's an incredibly tough schedule. Without looking at every team's schedule I'd guess that the Bills likely have had one of the toughest schedules in the league.
So, taken in all, the new schemes, the rookies playing, the shuffling on the OL and the much, much tougher schedule this year it's actually pretty surprising that the team would be only one game off where they were last year. I’m not sure how anybody could think that this team could have a much better record at this point in the season.
