Interesting article. I would also suggest that Pat Kelly would be a candidate. He would be in line to go to Bakersfield, but may have the tenure to take the Dayton job instead if he would prefer to be there without losing his place in the pecking order. Of course, if Sweet or Bell leave for whatever reason, I would expect Kelly would move up a level. Between Kelly, Deshields, and Griffey, those would seem to be the top three candidates, but there is always a chance of someone coming in from out of the blue. Dave Collins would take the job if offered (he lives just outside of Dayton) if he does not wind up in Atlanta, as some are suggesting he will.
Edit: The other name that could enter the mix is Julio Garcia, the Reds AZL manager in 2009, who managed in the Midwest League from 2001-'05.
