Of course every scheme is "sound" on paper. I'm sure Donofrio's system on paper is effective. But when he runs it in the real world, it doesn't always fit the players he has. This is the main issue most of us have - square peg, round hole. For those players that defend Donofrio's scheme, they readily admit that he's not aggressive enough (which is another criticism of his).
His scheme isn't effective. It's effective in his mind.
The best we can hope from this scheme is the Florida performance. Offenses, elite or ****ty, will march up and down the field on us at will just like they did.
The only thing we can hope for is that when they get to the redzone, our team bows up, does that stupid arm tug thing they do and either somehow forces a turnover or holds the opposing team to a field goal. Remember, yards don't matter.
