I think you go with the model that worked for us (young up & comer) versus our old model (old retread or AQ coordinator with no HC experience). Stokely worked pretty well under the old model and if he had had the current administration and support structure maybe he would have even been more successful. However, he was the exception. While we only have a limited data set with the new model, it has been wildly successful.
Of course, I am hoping we keep Hud and do not have to go through this experiment.
