Re: We cannot win a championship if....
I've been watching some more, and come back to the same conclusion.
Probably, the best inside look to Wade's scheme is to listen to Troy Aikman.
He's kinda boring in a methodological way, but he does hit the nail on the head when he said that offense can't not really key on his defensive look.
The variations are always there; they are just not easy to detect with normal eyes.
The concept of match-zone/match-man in combination with straight man and a slew of zone concepts can be tied up together in a neat package, if only the players can execute them. It does require the guys to work together (J Jo and KJax have been operating very well out of that concept.) The rest of the team has to follow suit. In short area, you just have to be able to cover man; that's all there is to it. You may have a little help here and there, but you can't rely on it.
It is really a tough deal for the D nowadays, you just have to stick to your main concept. There are holes in the zone and there are drawbacks in man. Wade's match-zone concept offer the expansion to go either way.
It all boils down to execution.
There are enough variations within the scheme to move either way, zone or man.
