Part of the problem when this is discussed - the "upsets happen" mantra - is that the impact of an upset loss is substantially higher for D1A teams than those at lower levels. Coaches at the elites have invested the time to understand the game thoroughly and do what's necessary to succeeed in all of the facets - recruiting, gameplay, etc. When they are denied an opportunity at an NC simply because the engine decided to randomly crap on them, it's beyond frustrating.
