I would go with with Francona being number 1 and Dick Williams being number 2. If Cora stands the test of time and deals with the issues that always come up when things don't go as planned, I'm thinking that he could become historic.
I will say that even though based on the record and because of the type of person that he is, I go with Francona but it isn't without some reservation. I might be the only one here who feels uncomfortable with the way he left Boston regardless of whether all the reasons were right. Although I like chicken and beer immensely, that incident did not sit well with me. I think that Cora might be tougher than we think behind the closed doors. DD has brought in some wonderful guys with respect to overall attitude and approach but I also think that Cora has had a great impact in who is currently playing and who has and is being brought in.
