I don't really understand what it means to know if a guy can manage at the ML level. It's not like it's a skill, like hitting a curve ball. I think far too much importance is given to tenure as a major league manager, that's why so many guys are recycled through the system. I think you are severly oversimplifying things by saying managing is not a skill. Decision making, strategy, knowledge, play relationships, etc all involve skill. No manager search will be needed by your criteria, just pull somebody off of the streets. I said it's not like a skill such as hitting a curveball. I didn't say it took no skill. And I didn't come close to suggesting you could just pull somebody off the streets. I think managers are vastly overrated, and often times do more harm than good. The best managers keep their players in-line and motivated, then sit back and watch them play. It's not like football where designing and calling the right plays can determine the outcome of the season. Some managers are better for really young teams, some are better for extreme veteran teams. Most managers that have had any success, have also had extreme failure. The managers who hurt their team the most are the managers who try to put their signature on every move, looking to "make things happen" by constantly calling for pitchouts (as Dusty often does with pitchers who have control problems), stealing bases, bunting etc. Just keep the egos in check, keep 'em motivated. Rest them and use them properly and it's a fairly simple job, the outcome of which should be determined by the skill of the players on the field.
