I too was at the September SCU/ND game and several SCU games thereafter. The Broncos did not switch their formation, they remained in a 4 back set the entire season. The exposure against UND the first time around was due to the loss of Jess Ballweg for the season in the opening game against Cal Poly, and the season ending injury suffered by Carrie Schuler earlier in the ND game. This left a giant hole in the central back area that Thorlakson and Chapman were able to easily exploit for the final 10-15 minutes of the game. As the season went on, Jordan Angeli (freshman) really matured as a player and the defense really came together. The lack of the typical attacking/possession style was evident all season. I would attribute this to the outside backs (Esquivel and Dalmy) and to a lesser extent, the defensive central mid (Osborne), playing quite a bit more conservatively. We did get to see flashes of Esquivel and Dalmy making some overlaping runs which quite visibly boosted the offensive chances, but not as often as Bronco fans would have hoped. Both ND Head Coach and Assistant were quoted about SCU 5 backs! SCU played Sigler and Bowen as center backs (with Angeli man marking Thorlakson) Dalmy and Esquivel as outside backs. So, SCU did change tactically to adjust to ND just like they did against Portland (Sinclair).
