Look, I feel like this is played out, but let's agree on this: Mangini's a football guy and he'd tell you that NFL success is measured in a consistent and simple way: wins and losses. The bottom line is the bottom line.
And going from 5-11 ending with a 4-game winning streak to 5-11 ending with a 4-game losing streak isn't progress, no matter how much lipstick you put on that pig, like changes in culture or being less hated than before or whatever. It's at best stagnant.
