AFC Championship Line Movement: Kansas City Chiefs 
at Baltimore Ravens 
The Baltimore Ravens against the Kansas City Chiefs is lining up to be one of the best AFC Championship games on paper we have seen in recent memory. The Chiefs are in an unfamiliar position being road underdogs for the second week in a row.
The Ravens looked impressive in their win against the Texans, 34-10, while the Chiefs beat the Bills again, 27-24. The Chiefs have caught some breaks in the playoffs facing the banged-up Dolphins and Bills. The Ravens come into the game in relatively good health. There is also a lot to be said for the Ravens dominating the Texans in the second half, while the Chiefs had to go down to the wire against the Bills.
I will go over the trends in detail more below, but the narrative of Patrick Mahomes as an underdog cannot be ignored. This is more of an informational article to help you make decisions, but I am very leary about EVERYONE being on the Chiefs again and I think people are overlooking what the Ravens have done. The Chiefs have some key injuries that need to be considered.
The SHARP money is on the Ravens' moneyline.
Odds
Chiefs: Spread (+3.5) -108, Moneyline +154; Projected Score 20.5 points
Ravens: Spread (-3.5) -112, Moneyline -185; Projected Score 24.0 points
Game Total: 44.5 points
Totaling bets thus far, 63 percent of the money and 64 percent of the bets are on the Chiefs. There is 59 percent of the money on the Chiefs' moneyline, but 61 percent of the bets is on the Ravens. There is 97 percent of the money and 93 percent of the bets on the OVER.
Trends
Kansas City is 11-2 straight up in its last 13 on the road
Baltimore is 10-1 straight up and 8-3 against the spread in its last 11 games (excluding Week 18)
Mahomes is 9-1-1 (depending on what closing number is used) as a road underdog
The Ravens have scored at least 31 points with an average score of 39-19 in their last six home games as favorites
The Chiefs are 5-5 straight up in their last 10 with an average score of 19.3-18.9

Chiefs - G Joe Thuney, WR Kadarius Toney, OL Wanya Morris, LB Willie Gay, DT Derrick Nnadi, S Mike Edwards are listed as QUESTIONABLE
1/25 - RB Isiah Pacheco (toe) did not practice Wednesday, but is expected to play. Thuney did not practice and is looking very unlikely to play.
Ravens - CB Marlon Humphrey, WR Tylan Wallace, LB Del'Shawn Phillips are listed as QUESTIONABLE
There is still no news on the status of TE Mark Andrews
1/25 - It is looking like Humphrey and Andrews are going to play which should impact the line movement in favor of the Ravens.

NFC Championship Line Movement: Detroit Lions 
at San Francisco 49ers 
The Lions come into the NFC Championship game as the public darling, as they have never reached the Super Bowl. Being a public dog is dangerous and not a side that you generally want to follow. Especially when you look at the moneyline where 67 percent of the bets are on the 49ers which represents sharp money.
That being said, the Lions do thrive in the underdog role and the 49ers have not performed well as home favorites recently. A big storyline in this game is the health of 49ers WR Deebo Samuel who is listed as 50/50 to play. The 49ers are just 8-9 straight up without Samuel.
Odds
Lions: Spread (+7.0) -112, Moneyline +250; Projected Score 22.0 points
49ers: Spread (-7.0) -108, Moneyline -310; Projected Score 29.0 points
Game Total: 51.0 points
Totaling bets thus far, 75 percent of the money and 71 percent of the bets are on the Lions. There is 69 percent of the money on the Lions' moneyline, but 67 percent of the bets are on the 49ers. There is 69 percent of the money and 73 percent of the bets on the UNDER.

The Lions are 5-2 SU and 6-1 ATS in their last seven as road dogs
The 49ers are 8-9 all time without Deebo Samuel
The 49ers are 0-5 last 5 ATS as home favorites
Key Injuries
