Boughner seemed to try different styles this season: PP-style 5v5 breakout and possession offense, active sticks and attack the seams, goon it up, and keep-it-simple-stupid (current). And these had varying levels of success. I can buy the argument that this was a training and experimental season. But from a big picture view, it seems like a strategic failure because I'm not sure they really built up their scheme/system nor cranked up individual player values.
If it's Boughner that's throwing darts on system ideas, then the blame should be more on him. But, if Wilson and front office is dictating what Boughner needs to try (so they can collect their data, build models, and project how to spend their assets), then I'd place more of the blame on them.
