[Editor's note: This article has been updated to reflect Sunday's results.]

For the Baltimore Ravens and Detroit Lions, the playoffs are beginning well before the actual postseason starts. In reality for both teams, they begin Monday night.

Both the Ravens and Lions are fighting for playoff berths and are hanging on to those spots by head-to-head tiebreakers -- in the Lions' case for the NFC North title and for the Ravens, the No. 6 seed in the AFC.

The Ravens need to win to keep pace with Miami, which beat New England on Sunday, for a wild-card berth. The Lions need a win to keep pace with Chicago, which won Sunday at Cleveland.

ESPN.com Detroit Lions reporter Michael Rothstein and Baltimore Ravens reporter Jamison Hensley break down what might happen Monday and who might leave "Monday Night Football" still with a playoff berth in their hands.

Rothstein: Up until Sunday, Detroit's run defense had been very, very good. Add to that Ray Rice appears to be struggling this season. What's going on with Rice and does the Lions' stout run defense mean more of Monday night's game is on the shoulders of Joe Flacco?

Hensley: Rice's best two games over the past eight weeks have come against NFC North teams, but a lot of backs have had success against the Chicago Bears and Minnesota Vikings this year. The Ravens would love Rice to duplicate what LeSean McCoy (217 yards rushing) did against the Lions, but I'm pretty sure there's not going to be any snow in Ford Field. Getting the run game on track has been the biggest challenge for the Ravens, who are averaging a league-worst 3.0 yards per carry.

Baltimore hasn't abandoned the ground attack. The Ravens, though, haven't shown much confidence in it either. They have put the ball in the hands of their $120.6 million quarterback to win games. Flacco has thrown over 30 passes in nine of the past 10 games. The problem with that strategy has been the increase in turnovers. Flacco has thrown a career-worst 17 interceptions, including three Sunday. Only two quarterbacks -- Geno Smith and Eli Manning -- have thrown more.

Speaking of turnovers, why have the Lions had so much trouble holding onto the ball this year?

Rothstein: It's a combination of factors, starting with Matthew Stafford. In some ways -- and yes, weather is an excuse here -- Sunday's "fumbleathon" against Philadelphia can be attributed to the weather because so many of those miscues happened when visibility was nil and in blizzard-like conditions. But Stafford has thrown a lot of interceptions in the second half of the season and some of those are just poor reads with which he should be doing better. Others are the fault of his receivers, who lead the league in drops with 41, according to ESPN Stats & Information. Reggie Bush has had some fumbling issues, too, and that has been a major problem for the Lions' top free-agent acquisition. It really comes down to Bush improving his ball security and Stafford making smarter decisions.

You mention the Jimmy Smith-Calvin Johnson matchup in the video. Every team has kind of schemed differently for Johnson this season. What do you think the Ravens will do?

Hensley: The Ravens don't have their cornerbacks shadow the same receivers, but they will want Smith on Johnson as much as possible because he's their most physical defender. Smith is going to have to play better against Johnson than he did in the 2012 preseason. In the game, Smith was beaten by Johnson on a leaping, 18-yard touchdown. He later held Johnson when the receiver went past him on the next drive.

But Smith is playing with more confidence and more aggressiveness in his first full season starting. He has allowed only 22 catches over his past 10 games. That is an impressive total when you consider he has covered the likes of Cleveland’s Josh Gordon, Cincinnati’s A.J. Green, Chicago’s Brandon Marshall and Alshon Jeffery and Pittsburgh’s Antonio Brown during that time.

The Ravens have some speedy receivers as well with Torrey Smith and Jacoby Jones. Of course, Flacco will need time to get the ball to them. How difficult will it be for the Ravens to slow down the Lions' pass rush?

Rothstein: Depends which pass rush shows up. If it is the one that played in the last Green Bay game (seven sacks), then Flacco's success will be predicated on whether he can make the first read correctly. If the pass rush is less successful, then Flacco could have a big day. Much of it will depend on how many people Baltimore keeps home besides the five offensive linemen.

If Baltimore decides to try to block Ndamukong Suh one-on-one, it'll be a long night. The pass rush's success also will depend on rookie end Ziggy Ansah. If Ansah is healthy enough to play, he becomes a huge difference-maker for the Lions as teams have really struggled to deal with Suh on the inside and Ansah outside. If Ansah can't play -- he injured his shoulder against Philadelphia -- then that's a big bonus for the Ravens.

The Ravens were a Super Bowl team last year. Now, they appear to be very much in the middle of the pack. Did Ray Lewis and Anquan Boldin make that big of a difference?

Hensley: I would argue that the Ravens have missed a healthy Dennis Pitta (out 12 games with dislocated hip) and Jacoby Jones (injured knee in season opener) more than Boldin and Lewis. You can throw in there that the Ravens have missed the same production from Ray Rice as well. Offensively, the Ravens haven't had as much of a void with Boldin as previously thought. Torrey Smith has assumed the No. 1 receiver job, and rookie Marlon Brown has been a weapon in the red zone with six touchdowns. And defensively, there hasn't been much talk of the loss of Lewis because Daryl Smith has played so well in the middle. The Ravens defense is statistically much better than last year's group.

So, why has there been so much of a drop-off this year? The offensive line and Rice have been major disappointments. There have been too few running lanes and too many sacks allowed. The lack of a running game and the inability of Rice to make plays in the open field have hamstrung this offense. The other problem has been coming up short in close games. Last year, the Ravens had the NFL's most wins in games decided by three points or fewer. This year, Baltimore has the second-most losses (four) in such games. The Ravens have begun to find a way to win those close games recently, which is why they're back in the playoff race.

The Ravens have historically come through in these December games, which is why they've made the playoffs in each of the past five seasons. Do the Lions feel added pressure in times like these because they've made the playoffs only once since the 1999 season?

Rothstein: I don’t think they do, but there is a lot at stake for Detroit over these last three games. Besides the Lions' second playoff appearance in three seasons, this is a chance at Detroit’s first division title since 1993 and if the Lions don’t make the playoffs, there probably will be at least a conversation about Jim Schwartz’s future in Detroit.

So there are, without question, a lot of things weighing on the Lions. But for them it has been all about the mistakes they have been making and what they need to correct. Whether they do that over the last three games will essentially decide their fate.
