It sounds like Graves thought the windup wouldn't be a big deal and waited for ST to work on it. That mistake may have been costly. However, IIRC, Danny's pitching was so bad, he never had a chance to work on the windup (runners constantly on).
What I remember most about Danny's starts is that his pitches were consistently up in the zone. THAT (and the resistance to starting) proved to be Danny's undoing.
I'm hoping that Danny and the Reds now understand how much work needs to be invested in Danny to make the starting experiment work. It's easy to throw dollars at a problem expecting a fix - now they have to have the effort. IMO, Danny really screwed up. Hopefully, he will have the motivation not to look so bad given the opportunity this year.
