Yes - although his recent success has been a little up and down. And certainly tough guys COULD work - and Showalter has dealt with young teams before too.
IMO, a baseball manager is the closest equivalent of any sports coach to your own boss in the actual job you have (or the sort of boss you are depending on your profession). A guy can have clear boundaries, not be your friend per se ... but still a guy you should be able to discuss problems with, and someone who knows when to press a guy hard and when to provide some encouragement.
That's the thing with a guy like Tito. He is a terrific manager yes, but he would also probably embody a lot of what would be the best boss you ever had regardless of whatever job you had. (assuming he was qualified for that job etc etc etc)
