Well, Texas State's defense looked like a D1-AA school going against a big D1 school. They allowed 300 yards passing, 200 yards to a receiver, and 100 yards to an RB, first time A&M had ever achieved that in a single game. They almost allowed McNeal to become the first player in NCAA history to have back-to-back 300 yard throwing 100 yard rushing games (according to the announcers). Texas State only forced 2 punts all game (actually 3, but were called for roughing the kicker on 1 of them). So, asking them to stop A&M once when the Aggies were faced with possible defeat was probably too much, let alone twice.
It was a very good showing by Texas State though. They should handle their conference and perhaps put up a good showing in the D1-AA playoffs. They were ranked #14 in the nation going in, I wouldn't be surprised to see their ranking go up despite the loss.
