Every team in the league operates under those same conditions. But a number of other teams somehow manage to start the season looking way better than we do.
Offseason prep and pacing are a big part of coaching.
Tom Coughlin used to beat the sh-t out of his teams. They'd start the season looking like world beaters, then by late season they were done.
On the flipside, more "vet friendly coaches" would take it easier. They start looking slow and maybe a tad sloppy, but get better as seasons go along.
The best coaches though, find a way to start looking crisp up front and keep it going all year. Belichick tended to be good at this. Reid has likewise become a master over the last few years.
Bottom Line: Having your team ready to play is a coach's responsibility, and not just on a weekly basis. It's important coming into the season also.
