Yeah he is a strange fish but coaches have different ways that THEY think work, and that is what makes them different. Madge's philosophy has worked for him before. It obviously won't work without the correct group, just like other coach's philosophies don't.
I hate to use the term "perfect storm" but the stars have to align for the right coaching philosophy to match the squad. There are untold mismatches that produce failure and very few that produce dynasties. Bellamy, Robinson and Bennett SEEM to have the best methods, but they have had by far the best cattle available because of money. Bennett flopped when he hasn't had the money needed, the other 2 have never put the themselves in that position. I suspect they know that and never will.
I like the way Des does it because that is how I would go about it. Right or wrong way? I don't know.
