Teams are beginning to separate themselves as we enter the second half of the regular season. Quarterbacks are at the forefront and should be settled into their offenses.

Here are our top quarterback Over-Under passing total bets for Week 10.

*Odds subject to change

Buffalo Bills QB Josh Allen OVER 237.5 passing yards (-115) vs. Indianapolis Colts – DraftKings

Allen is having yet another Pro Bowl caliber season with 2,001 passing yards, 17 touchdowns and just two interceptions. He has thrown for over 237 yards in two of his last three games, falling just three yards short in the third game.

This week Allen has a great matchup against the Colts, who rank 26th in the NFL against the pass. The only quarterbacks to not throw for over 237 yards against Indianapolis are Tyler Huntley, Will Levis and Malik Willis, none of who are currently starters.

San Francisco 49ers QB Brock Purdy OVER 260.5 passing yards (-117) vs. Tampa Bay Buccaneers – Caesars Sportsbook

Purdy and the 49ers are entering this matchup well rested coming off of their bye week. They'll take on a Buccaneers defense that ranks 30th in the league against the pass, allowing over 260 passing yards in four of their last five games.

Purdy has thrown for over 260 yards four times this season and is getting wide receiver Deebo Samuel back from injury this week. Christian McCaffrey is also returning, who is one of the best pass catching running backs in the NFL.

Minnesota Vikings QB Sam Darnold OVER 243.5 (-114) vs. Jacksonville Jaguars – FanDuel

Darnold has one of the best sets of skill position players to work with in the NFL, which includes multi-time All-Pro receiver Justin Jefferson, speedster receiver Jordan Addison, and Pro Bowl tight end T.J. Hockenson.

Even running back Aaron Jones is a sneaky good receiving option out of the backfield. Darnold has eclipsed 243 passing yards in two of his last three games, and has an excellent matchup against the Jaguars' defense, which ranks 31st against the pass.

Chiefs QB Patrick Mahomes OVER 230.5 passing yards (-114) vs. Denver Broncos – FanDuel

After a tough start to the season statistically, Mahomes has averaged nearly 300 passing yards in three of his last four games. The resurgence of tight end Travis Kelce and the addition of wide receiver DeAndre Hopkins have helped Mahomes out tremendously.

Denver has a good secondary, but with Mahomes back in his groove and weapons at his disposal, 231 yards is very attainable.

Chicago Bears QB Caleb Williams UNDER 211.5 passing yards (-114) vs. New England Patriots – FanDuel

Williams has been wildly inconsistent during his rookie year. The Bears' offense has talent, but just can't seem to put it all together. The Patriots have been solid against the pass this season but weak against the run.

Chicago running back D'Andre Swift is running the ball well and will likely see a heavy workload in this matchup. With that in mind and Williams' production being disappointing more often than not, this is a safe bet.
