Every Sunday night, oddsmakers drop the upcoming week's NFL betting lines, and if you are wondering if the opening spreads look accurate, we've got you covered.Each week, FOX Sports Betting Analysts Geoff Schwartz, Sam Panayotovich and Jason McIntyre will break down the opening numbers in this space and point out if they think the line is too low, too high or just right.This week, we are down to two games, so let's jump into their analysis for the conference championship round!Lions @ 49ers (-7)ADVERTISEMENT We have a little case of recency bias here. It feels like an overreaction to the Lions covering against and the 49ers looking poor for three quarters before pulling out the victory late.The Lions defense has been torched in two playoff games (833 yards allowed!), outgained in both yards and yards per play. And now the Lions offense must leave the dome.If is a go, my gue s is this spread closes at -7.5. Ive been waiting all postseason for this matchup: Detroit against a great team.San Francisco was shell Solomon Hill Jersey shocked after Deebo Samuels first-quarter injury, but the Niners still found a way to beat despite playing their "C" game. I imagine they wont play that vanilla in back-to-back weeks.I also doubt the Lions can stop all of weapons. My opinion about how this game goes would align more with the spread, but this number is too low for how they price these matchup.The Niners did not play their best game on Saturday but still won. I expect to see a more well-rounded 49ers team on Sunday.Outside the offensive line, the Lions do not have the same talent as the 49ers. The last two Lions games played outdoors resulted in bad lo ses as well.Are the Chiefs peaking at the right time? Chiefs @ Ravens (-3.5) Baltimores top-rated defense will be a ma sive step up in competition for Kansas City, a team that feasted on banged-up and .Then theres . Theres nobody scarier in the league to bet against, and his presence will keep this line around 3. The "you have to take the points with Patrick Mahomes" narrative will be the storyline all week, but its telling this opened north of a field goal.The Chiefs found succe s against average defenses ranked 19th (Miami) and 12th (Buffalo) in DVOA, but now they step up in cla s to face the No. 1 defense in Baltimore. The Ravens permitted just one drive over 35 yards against the .One big note that is too good to pa s up: John Harbaugh is 1-4 against Andy Reid in the last five meetings. Baltimore is the better team. They are healthier after this weekend, they are at home, they have the MVP at quarterback and they are the more physical overall team.This line opening at 3.5 instead of 3 tells you that the books like the Ravens in this matchup.Jason McIntyre is the co-host of The Herd and a FOX Sports gambling analyst, and he also writes about the NFL and NBA Draft.
