we could be undefeated when Raffo comes in and I still wouldn't be convinced that it means anything at all. Raffo would still be coaching with Polk's players, under Polk's guidance, etc. I just can't believe that he would make any drastic changes in the few games / innings that he gets into. Polk has trained him and he would likely do nearly the same things as Polk.
Now, if Raffo were to get the job next year he may change things up a bit but it still wouldn't be anywhere near the changes that we may see by hiring through the national search.
