I find it's usually best to keep expectations reasonable when you're coming off a 4-13 season.
That being said, there's always a few writers who like to say things like "The Patriots are going to the Super Bowl" at the start of the season. Heck, we see that in the Jets press every year. They know people will forget if they're wrong but will remind the hell out of people if they're right (well, at least in theory for the Jets.)
So there will always be the "anything less than a Super Bowl is a failure even if we're coming off a last place finish with a brand new coach" crowd out there - but for my part I would have been prepared to call 10 wins a HUGE success for the first year and I officially predicted 9 wins.
10 wins to me would make us a contender and I know there were a lot of folks here who expected that at the very least, getting us back t respectability so we wouldn't be snubbed by free agents in the off season.
All the rest of this season is gravy as Maye and the roster will only get better in future seasons. It would still be best not to adopt a "anything less than a Super Bowl is a failure" even now, as we have a solid foundation for the next dynasty regardless of how they finish this season!
