Luvullo is an interesting possibility, as well. He would be worth looking into, though Cleveland may want to hold on to him--there are some fans in the northern part of the state who are not fans of Eric Wedge!
I think that the Reds' front office--whether that is Krivsky, Jocketty (as has been rumored), or someone else--needs to sit down between now and the end of the season (or shortly after the season, if it is someone other than Wayne) and establish parameters and guidelines pertaining to the direction that it wants the club to follow, and then interview a number of candidates (both high-profile and lesser-known) to find the best fit. If Pete Mackanin does well in the second half of the season, I am not opposed to giving him an interview, should he be interested. But I don't want the Reds to simply hand him the reins, as they did with Dave Miley and Jerry Narron. It just isn't good business sense. (And don't get me wrong--I think Jerry is an outstanding person with great moral character. I wish him nothing but the best.)
