So why doesn't anybody want him? Why didn't Dallas lock him up for multiple years? Why didn't the league just drop the whole thing?
Excuse me if I don't check my brain at the door. This is plain as day.
Yes it is plain as day.
It's simple. It's business.
Every team knew Goodell was going to use this case as a "mulligan" for the Ray Rice fiasco. They knew the NFL's image was under scrutiny, and Gooddell, as Supreme Overlord Judge McAwesome of the NFL, was going to do everything in his power to give Hardy not only the max, but to delay proceedings as long as possible. They knew he'd delay, and he'd appoint a rubber stamping lackey as arbitrator to support the decision, and it'd eventually have to be settled in Federal Court, with an unknown timeline.
I'm sure plenty of teams "wanted" him, who doesn't want a potential All-Pro DE? They didn't want to pay for a guy who they knew was probably going to get a ridiculous suspension from Goodell to start the season, and that's exactly what happened. Queue all my previous points, and it's easy to see why he didn't have many suitors. Also, a smaller point, with the big "domestic violence in the NFL" image going on, some teams probably saw him as an image issue.
The League isn't "dropping the whole thing" because they have an image, and they see it as tarnished, and they think they *have* to pursue this to the bitter end to help shine that image of theirs that's been quite scuffed due to their own actions in precedent.
As far as the settlement, settlements never imply guilt or innocence, so if he did "pay her off" that means absolutely nothing. It simply means it was easier to hand someone a check than to keep going through the legal process because the only ones getting paid in that scenario are the lawyers. It's easier and less stressful to settle 90% of the time.
Additionally, since you're so concerned about settlements implying guilt or innocence. The party that receives the settlement never settles if they have an open and shut case, or even a case with a high probability of winning in court. So the action of settling is not nearly as conclusive as you would lead people to believe.
