I think he's legitimately been doing this, even on a micromanaged play-by-play in a series while watching the game live, basis. Like Drew's "mental reps", I'd bet he was taking "mental coaching reps" during game and probably cringed at the offensive play calling. It would not surprise me at all for him to be thinking, "I would have made X adjustment in game 1, had Y game plan for game 2, etc... and had us at 9-4, running away with the division!"
