Top football betting apps for NFL Week 18 Saturday and Sunday games As of Friday, the Ravens are huge favorites over the Browns. A win for Lamar Jackson and the Ravens would give them the AFC North division title. There’s little doubt that Baltimore will win this game; it’s just a matter of by how much. For the Bengals and Steelers, this game could carry huge weight for both teams. Joe Burrow and Cincinnati need a win and some help to get into the AFC Playoffs. Russell Wilson and Pittsburgh need help from the Browns to have a shot at the AFC North. If the Ravens win in the early game, the Steelers have nothing to play for in the game. They will be a Wild Card team. Still, Burrow has been the best quarterback in the NFL over the last month or so. If he can get the Bengals into the playoffs, he will likely win the NFL MVP. But, again, they need help. Cinci needs the Miami Dolphins and Denver Broncos to lose their games on Sunday. Given that, the Bengals are a slight favorite at most sportsbooks. Of the Sunday games, three will draw the most interest, and the Broncos have the simplest path to the final AFC Playoff spot. If Denver beats the Chiefs in a game that kicks off at 4:25 p.m. ET, it gets into the playoffs. The Dolphins need Cincinnati to lose on Saturday night to have a shot and then beat the Jets. Miami and New York also get underway at 4:25 p.m. ET. The final game of the regular season is a doozy. The Vikings and Lions are playing for the NFC North and the No. 1 seed in the NFC. The loser of this SNF game will be a Wild Card team. Both teams come into this contest with 14-2 records. The game starts at 8:20 p.m. ET and airs on NBC. In all, the Week 18 games are good opportunities to begin the sports betting journey. The best sportsbooks have plenty of offers to fit your needs in a responsible way.
