It's because even he knows that the Irish have no short yardage power running game in one possession games at crunch time (think multiple times vs Ga), He chose to let BW (whose touch, accuracy and consistency are questionable at best) throw a swing pass to and equally inconsistent tight end rather than lining up and running right at the Navy's undersized DL or letting BW try to do it with his feet.
Until the Irish can grind the clock in the closing minutes of one possession games they will continue to lose more than their share of them. We are playing a team next week that can do so and I hope we don't have to pay again for this huge weakness in BK's offensive scheme not to mention his irrational play calling in the closing minutes of games.
