I certainly didn't, as you don't have to be a genius to figure this team needs time to come together and gel. However, there were a TON of homers who were basing this year on past year's success. For example, I thought we could have a 11-5/12-4 record and have a shot at making the playoffs--that prediction was based on the fact that we face a very hard schedule. People can deny this fact all they want, but there is no doubt the schedule will be challenging to say the least.
There are actually people here who keep forcing themselves to deny this fact, I even heard some claiming "they didn't see any challenges the first half of the season!!"
As a matter of fact, some even were predicting another unbeaten season, it's almost like they haven't ever watched football before. We'll lose on the road, we'll lose at home, we'll lose in the division once or twice, and we'll lose a game no one thought we'd lose. It's just the nature of football, where the parity keeps rising in this league.
So to answer the OP's question, some certainly did expect automatic perfection--why, I'm not sure though? Just take a look at the season's prediction threads, and the threads on us being "favored" in every single game this year
Some are beer bonging the kool-aid, not even chugging it, let alone sipping it slowly. When you set yourself up like that, it's just asking for failure. There are many teams in this league who are damn good, and can win in any single game.
