If I recall it took Mr I a few years before he caught on. Of course he had to dig out of the rubble left my Mr Domino's "pizza". Mike had the passion just wasn't up on the working knowledge of an MLB team. He relied on Jerry Reinsdorf for a while on the political ins and outs. I think it was Bud Selig that helped with the hiring of John McHale Jr who brought in Randy Smith before Mr I decided on Dave Dombrowski a few years later. Basically Mr I had the Tigers wandering thru the wilderness for about 10 years before they got their act somewhat together.
Unfortunately MLB's current leadership is no help to the teams who may be struggling, other than making stupid rule changes and gimmicks. Chris may be a decent caretaker, he lacks the passion.
And yes it's time to move on from AA. Move him upstairs make him an executive vp or something.
