The $175m was the floor. Even at that it was probably going to be 2-3 years of lower cap to break even to money lost. If they didnt borrow from future cap then the floor would be much lower than the $175m this year. It will rake 2-3 years of reduced cap to recoup $50m+ in attendance dollars lost.
Its my assumption that, that $180m is the adjustment for this season(from $175m), not that it will still be more to make on top of it.
We all know what happens when we assume something though.
There really aren't any great defenses. At least not for any length of time. Sure , a few teams D will play at a high level for a while, but not game in/game out for a significant time.
While the great Offense's, with the Elite QB's, are there consistently.
