As has been stated many times, ULM's coach was not going to just sit there and not make adjustments.
Chandler also would not have had a scripted drive on his third series.
Also two successful drives was not enough to completely erase the memory of Chandler only passing for 38 yards the week before.
What was also not forgotten was how the quarterbacks one-two punch had scored on every single possession 3 quarters prior.
Desormeaux may have been out coached but not for the reason you stated.
