“We all have to look ourselves in the mirror, and we just have to get better from it,” said Head Coach Matt Nagy, “because that’s not the standard, and we’ve got to keep the standard the standard.”

Nagy said there were some defensive bright spots like a big red zone stop on third and one. But the issues came down to calls new defensive coordinator Sean Desai would like back – and players simply not executing.

“This was Sean’s first game calling and it was our first game of 2021, and we understand that’s not good enough,” Nagy said. “We want to be better.”
