I recognize the point you are arguing, but for the record, that's not the definition of "innocent."
Even when there is a trial and one is found "not guilty," that is not the same thing as being innocent.
Personally, I don't think for a second that Zeke is innocent. I have no idea whether or not he actually did something bad enough to to meet a legal standard of domestic violence; clearly, the prosecutor's office didn't think there was enough evidence to get a guilty verdict. But no way I think he's actually innocent or didn't violate league standards.
I can't stand Roger Goddell, but in this case, he distanced himself a bit with a panel of non-NFL people who looked at all the evidence and came to the conclusion he wasn't "innocent." Goddell is responsible for the length of the suspension, but most of us feared this all along, especially based on his other behaviors since.
I've been a Cowboys fan since 1966, and I always will be, but even though I don't approve of many ways the NFL does business or treats its employees, including head injuries, veteran treatment, and even this suspension, I refuse to defend Zeke just because he's a great player for our team. Zeke has already blown any chance to be in the same sentence as Smith and Dorsett when it comes to being Cowboy RBs, but he still has a chance to right the ship and have a long, successful career as a Cowboy. At least his apology gives me hope; now he has to prove he meant the things he said.
