I know what I don't want.
I still have residual bad taste in my mouth from the Dave Miley era, so my top criteria is no minor league managers without ML experience... not from Louisville, not from anywhere.
With a fairly young team, I don't want the Reds to roll the dice on a beginner with zero managerial experience, either. That rules out Corky and Rolen.
For the same generation-gap reason, I don't want them to hire a screamer, either. That rules out Bobby Valentine and Sweet Lou.
I'm willing to sit back and see who Walt would select, and I'm hopeful it wouldn't be any of the above.
