In the Jets’ first two preseason games, the defense clearly was the strength of the team. Even so, inside linebacker Demario Davis wants things to be better. “The backbone of this team is going to be the defense,” he said, “so we have to perform at a high level every time. No excuse.”

The Jets limited the Titans to a field goal in a 7-3 win in the preseason opener, but the Lions moved the ball fairly well against the starters in the first half. The Jets trailed 13-0 at halftime. “A couple of times, we were able to get off the field pretty quickly,” Davis said. “[Defending] quick passes, there were some good things we did.”

He believes it has to be better, particularly with an offense that may take time — a lot of time — to find itself. “This is a challenge, and we accept the challenge,” he said. “We embrace it.”
