Breaking down the Detroit Lions position battles and depth chart entering the preseason matchup with the Miami Dolphins

The best example came at the end of practice. The Dolphins’ offense had the same situational drill as the Lions: Down 24-20, ball on the 48-yard line, 59 seconds left, fourth quarter. It didn’t go half as well as it did for the Lions offense.

▶ The Lions dominated the first day of joint practices against the Dolphins, full stop. The offense dominated; the defense dominated; even punter Jack Fox put a ball out of bounds at the 2-yard line. It was a bloodbath. The first teams took a majority of reps, since joint practices are in some way a substitute for playing in preseason.
