Cowboys head coach Jason Garrett released a statement thanking fired defensive coordinator Rob Ryan and briefly explaining the decision:
"I want to express my appreciation to Rob for all of his efforts and contributions to the Cowboys over the past two years. At this time, the decision has been made to move forward in a different direction philosophically on defense. I have an immense amount of respect for Rob as a person and as a football coach and I wish him and his family the very best."
The one-sentence explanation about a philosophical change could be considered a strong hint the Cowboys will change to a 4-3 scheme. Stay tuned.
