If there has been one thing that has been incredibly frustrating about the 2018 Detroit Lions it’s their extreme turnaround on special teams. Last year Jahlani Tavai Jersey Mens , the Lions had one of the best units in the league, both in terms of returning abilities and coverage units. That has all completely changed, and the Lions have already done something about it. On Monday night the Lions announced that they have fired special teams coach Joe Marciano. Marciano had been the team’s special teams coordinator since the 2015 season. Head coach Matt Patricia offered this statement on the move:In 2018, the Lions rank 24th in average kick return yards allowed and dead-last in average punt return yards allowed. Additionally, the Lions struggled with penalties on their special teams units. On Sunday against the Vikings alone Kenny Golladay Jersey , the Lions had three special teams penalties, which is exactly the kind of problem that has put the Lions offense behind the eight ball.At the moment, the Lions have not announced a replacement, but they do have an assistant special teams coach, Devin Fitzsimmons Michael Roberts Jersey , on staff. The Lions’ top running back is going to be out for a while — but not as long a while as some feared.After medical tests today, Kerryon Johnson is considered week to week with a knee sprain, a league source tells PFT.Considering that the Lions play on Thanksgiving, we can safely say he won’t play in that game, and maybe won’t play a few more weeks beyond Thursday. But any time a running back limps off the field with a knee injury there are fears that it could be something more serious Travis Fulgham Detroit Lions Jersey , and those fears have been assuaged.Still, any game without Johnson is a game in which the Lions’ running attack may be nonexistent. Johnson has single-handedly given the Lions a running attack this season: Johnson has averaged 5.4 yards a carry, while the Lions’ other running back, LeGarrette Blount, has averaged 2.3 yards a carry.So the Lions are going to have a tough time running the ball on Thursday against the Bears. But at least they’re not worried about the long-term health of their promising rookie runner.
