"I accept the responsibility for that not being done better," Del Rio said. "There were 38 seconds and we only got two snaps off. That's not good.

I must make sure that our staff and our 11 offensive players that are involved in that situation handle that much better. It was not acceptable. It didn't give us enough opportunities there at the end to steal that win."
