Fan expectations are high as NFL teams usher in new coaches, but the results may not match the hype. Coaches like Ben Johnson in Chicago are establishing ambitious goals, promising a winning mentality early on. The New York Jets, with a new perspective under Aaron Glenn, might need patience as they attempt to revitalize a struggling franchise. Meanwhile, the Dallas Cowboys face a tough reality as their coaching changes may not be enough to overcome decades of unmet expectations.

The Jaguars' situation shows promise with a supportive environment for new head coach Doug Pederson, while the Bears are looking to redefine their identity. However, the Cowboys' high-pressure environment could spell trouble for Brian Schottenheimer if results don't come quickly. In the end, optimism abounds across the league, but fans must be prepared for the reality that rebuilding takes time.
