​Dan Campbell knew what this was by halftime. He barked it into the CBS cameras.“We gotta calm down … and then we GOTTA GO! We can’t be messing around!”Exactly. When playing a team that is 1-6, a good team often finds itself inexplicably fumbling and bumbling. It’s like when you can’t get that first piece of plastic to peel off the box. You start normal, then you try your fingernails, then you get frustrated, and you wind up screaming to yourself, “Why is this so damn hard?”That was the Detroit Lions for much of Sunday’s game in Miami against the low-win but high-effort Dolphins. Detroit’s first drive used up nearly seven minutes but ended with a sack of Jared Goff on third-and-goal. A field goal had to suffice.Their second drive ended in an interception, when Goff was pressured and a defender hit his arm as he tried to pass.Their third drive ended with a punt.Their fourth drive, after starting with great field position, fizzled when Jahmyr Gibbs was yanked down twice in a row for thre- yard losses and Goff was pressured into a scramble.Another field goal.The NFL’s highest-flying offense was hovering very close to the ground.Fortunately, Miami couldn’t take advantage. They punted twice, notched a field goal, and wasted an 11-play drive with a doink off the uprights by their kicker, Zane Gonzalez.Halftime ended at Lions 6, Miami 3. Which is what led Campbell to his “we can’t be messing around” critique, which I’m sure he delivered in the locker room with a fervor that would have scared the average TV viewer.And eventually, they did stop messing around. And they finally brought home a 19-9 win that may have certain critics attacking them for, well, not being able to get the plastic off a box faster than that.They’d be wrong.[ LIVE REACTIONS: Make the “Freep Sports Show” your go-to Detroit/Michigan sports podcast, available anywhere you listen (Apple or Spotify).

It swirled around practice all week. When one football player sees another football player face down and not moving, it stays with them − believe me. Dealing with Campbell’s health uncertainly, then getting a positive message from him midweek, then having to focus on an opponent that should be easy to beat … well, all that is a perfect recipe for the old trap game, where you go home shaking your head saying, “How did we lose to them?”That didn’t happen Sunday against the Dolphins, and the Lions first deserve credit for that. Four plays into the second half, safety Chuck Clark snagged a Malik Willis pass and turned into a running back, cutting angles and using blocks. He returned the ball 34 yards to the Miami 26. For a maligned secondary, it was a sweet moment and a turnaround, one that invoked Campbell’s “no more messing around.”LIONS GRA
