Throughout this week, we are going to go through the 10 plays (with some liberties for moments) that shaped the 2015 season for the Detroit Lions.

See the complete list as it is unveiled here.

The play: The Lions were trailing 13-10 to Seattle with 1:51 left in the fourth quarter and had a third-and-1 from the Seahawks’ 11-yard line. Quarterback Matthew Stafford found his all-too-familiar target, Calvin Johnson, and Johnson ran toward the end zone. Johnson dove for the end zone, extending the ball out. Seattle safety Kam Chancellor knocked the ball out of Johnson’s hands and it bounced toward the back of the end zone. Seahawks linebacker K.J. Wright then batted the ball out of the end zone to keep the Lions from recovering. The refs called a touchback, giving Seattle the ball with the lead and less than two minutes left.

The situation: The play was incorrectly officiated and Wright should have been assessed a penalty, giving the Lions the ball on the 1-yard line with a chance to run some clock or score a touchdown. The NFL’s officiating czar, Dean Blandino, said the officials made the wrong call and that Detroit should have been given the ball. In the aftermath, Lions owner Martha Ford spoke up to NFL commissioner Roger Goodell about the call. Lions coach Jim Caldwell tried to downplay the effect of the play, but the Lions were blown out 42-17 the next week by Arizona. What could have been a 1-3 start turned to 0-5. Of course, the Lions would not have been in that situation had Johnson not fumbled at the goal line.

The reason it mattered: The Lions entered the Monday Night Football matchup at 0-3 and desperate for a win. Before the game, Lions safety James Ihedigbo acknowledged that a win over Seattle could change the trajectory of their season. It almost happened. Seattle still would have gotten the ball back with time left had Johnson scored. If he hadn’t, the Lions could have milked the clock and still at least tied the game, but the Seahawks would have had an opportunity. And the Lions could have gotten the ball back had they stopped Seattle after the wrong call.

At 0-4, the loss put the Lions in an almost impossible position for a winning season and playoff berth. They rebounded to 7-9, but the loss continued Detroit’s slide to be the last winless team in the NFL (0-5). The Lions started 1-7 and fired five people (team president Tom Lewand, general manager Martin Mayhew, offensive coordinator Joe Lombardi and offensive line coaches Jeremiah Washburn and Terry Heffernan) before the second half of the season.

From a bigger perspective, it brought even more attention to the league’s questionable officiating in late-game situations. It renewed the call for more plays and situations to be reviewable and appears to be part of the impetus to have the league office involved in replay during the playoffs to make sure they get calls correct.

What Jim Caldwell said about the batted ball call, beyond calling it “ridiculous:” “What can you do, you know what I mean? We’re not going to cry about it, that’s for sure. We just got to tee it up and go at it again.”

What James Ihedigbo said about officiating: “It’s not going to change it to a win. I mean, they got to be held accountable, just as players are in terms of equipment violations, whatever it may be. There’s a standard players are held to on the field. There’s a standard the coaches are held to on the field. There’s a standard that teams are held to on the field. There has to be a standard that officials are held to as well. You can’t just apologize.”

NFL head of officials Dean Blandino on the play: “The back judge was on the play and in his judgment he didn’t feel it was an overt act, so he didn’t throw the flag. In looking at the replays, it looked like a bat so the enforcement would be basically we would go back to the spot of the fumble and Detroit would keep the football.”

Seattle linebacker K.J. Wright on the batted ball: “I wanted to just knock it out of bounds and not try to catch it and fumble it. Was just trying to make a good play for my team. You can’t hit it backwards, and you can’t intentionally, I guess, knock it out. But at the time I wasn’t thinking that. I was just trying to not mess up the game. So I know now.”

Arizona coach Bruce Arians on what he would have been like if that happened to his team: “I’d still be in the hospital, high blood pressure. Every week now we have a call in a game that is determining outcomes of games.”
