I voted yes, but here let me add an asterisk.
I am "more" optimistic than I was about last year, which really isn't saying much. The Cowboys set themselves up to fail last season. At least things are not status quo on the coaching staff anymore. And while not many fans care about the moves they made in free agency....at least they TRIED.
A solid draft might even convince me. Get a true number two receiver, a true number one back, and a corner that can play and let's roll with it.
