Tony Daniel has literally no experience as a writer, aside from a few projects here and there he was merely the artist on Morrison's run on Batman. He was going about his day when Didio called him and told him that he was writing Battle for the Cowl. I can only imagine his reaction.
In this interview Daniel said, "I plotted and scripted everything from scratch. That’s why they chose me to write it, they liked what I had in mind." Clearly he recalled sharing ideas with the bosses before he got the job.
Furthermore, in his previous Newsarama interview, Daniel talked about presenting ideas to editor Mike Marts in conversation, repeating his interest in an email, speaking to DiDio by phone two days later, and finally sending in a first draft before he was sure of the assignment.
We don't have to "imagine [Daniel's] reaction." He laid out the sequence of events for us. I don't defend the result, but I think it's worthwhile starting from the information that's available.
It's still obvious that Daniel wasn't DC's first choice, and the company was coming up against a deadline and had to find someone to crank this baby out. Your observations about sloppy artwork might imply that Daniel was spreading himself too thin, or caught in too tight a schedule.
