Four young quarterbacks will take center stage when the Philadelphia Eagles and San Francisco 49ers collide in the 2023 NFC Championship Game and the Kansas City Chiefs and Cincinnati Bengals square off in the 2023 AFC Championship Game on Sunday. The average age of the 49ers' Brock Purdy (23), the Eagles' Jalen Hurts (24), the Bengals' Joe Burrow (26) and the Chiefs' Patrick Mahomes (27) is 25 years and 98 days, the youngest average age of starting quarterbacks on Conference Championship Sunday ever. Two of those quarterbacks will advance to Super Bowl 57 on Feb. 12. Philadelphia is a 2.5-point favorite in the latest NFL odds from Caesars Sportsbook in the NFC Championship Game 2023, while Kansas City is a 1.5-point favorite in the latest NFL spreads in the AFC Championship Game 2023.

Hartstein went 68-50 ATS and 8-3 on money-line plays last season for a profit of $1,552.

Hartstein has locked in his confident picks for this weekend's conference championship games and has a parlay that would pay 10-1. You can only see his picks and analysis at SportsLine.

Top NFL Conference Championship Game parlay picks

After closely studying both championship games, Hartstein is leaning Under the point total in Chiefs vs. Bengals. Chiefs quarterback Patrick Mahomes has been dealing with a high ankle sprain he incurred during the Divisional Round win over Jacksonville. Kansas City coach Andy Reid said he will start against the Bengals.

Since Christmas Eve, both teams have been playing elite defense. Cincinnati ranks third in the NFL over that time in scoring defense (15.3 points per game allowed), while Kansas City is fifth (16.8). "I'm leaning Under on Sunday due to Patrick Mahomes' possible limitations, the Bengals' much-improved defense down the stretch and the balanced approach I expect from both teams," Hartstein told SportsLine. You can see the rest of Hartstein's Conference Championship Game NFL parlay picks at SportsLine.
