Mark Schlereth doesn't think Colin Kaepernick can iron out his flaws because he has a tendency to revert to what he's most comfortable with. (0:53)

To coincide with the 28-hour ESPN Fantasy Football Marathon presented by Draft Kings, NFL Nation reporters are taking a position-by-position look at the teams they cover.

On Monday: Over/under on starting-quarterback performance in 2016, based on their ESPN fantasy projections. Click the links after each team to view the full posts.

Arizona Cardinals: Carson Palmer was one of three players to receive an MVP vote after turning in the best season of his career, but even at 36 years old, he can put up another monstrous season in 2016. Read more.

Atlanta Falcons: Matt Ryan will throw deeper, pick up more passing yards in 2016, but his touchdown numbers could decline. Read more.

Baltimore Ravens: Joe Flacco has never been a sought-after fantasy quarterback, and there will be increasing concerns with Flacco playing on a surgically-repaired left knee. But this season is shaping up to be a career year. Read more.

Buffalo Bills: Tyrod Taylor's fantasy production should tick up in 2016, but it could be linked to the health of wide receiver Sammy Watkins and tight end Charles Clay. Read more.

Carolina Panthers: Cam Newton has a chance to exceed his 2015 MVP season with the return of wide receiver Kelvin Benjamin. Read more.

Chicago Bears: Jay Cutler is a polarizing figure not just for Bears fans, but also fantasy-football owners. Cutler again faces the daunting task of putting up big fantasy numbers while operating in a run-heavy, conservative offense. Read more.

Cincinnati Bengals: Andy Dalton will generally be more productive in 2016, building off his strong 2015, but he could have fewer passing yards. Read more.

Cleveland Browns: It's always possible that Robert Griffin III could revive his career under Browns coach Hue Jackson's tutelage, but expecting that with certainty is the height of folly. Read more.

Dallas Cowboys: Tony Romo has been a dream quarterback in fantasy football. As he begins his 10th full season as starter, he has a complete understanding of the scheme and, as a result, should put up big numbers. Read more.

Denver Broncos: With an elite defense and a pumped-up run game, either of the top-two Broncos QB options figure to put up better numbers than their projections. Read more.

Detroit Lions: Due to a new offense, comfort with his coordinator and a diversification of offensive weapons, expect a big season from Matthew Stafford in 2016. Read more.

Green Bay Packers: Aaron Rodgers is coming off a down year -- by his standards -- yet still threw for 3,821 yards and 31 touchdowns with only eight interceptions. Much more is expected from him and the Packers' offense this season. Read more.

Houston Texans: There is a lot of pressure for Brock Osweiler's numbers to reflect the four-year, $72 million contract he signed with the Texans. Will he underperform expectations? Read more.

Indianapolis Colts: Andrew Luck will silence any doubters, fantasy or otherwise, who don't think he can bounce back from the worst season of his NFL career. Read more.

Jacksonville Jaguars: Blake Bortles had a breakout season in 2015, setting franchise records for touchdown passes (35) and passing yards (4,428). Can he duplicate those kinds of numbers in 2016? Read more.

Kansas City Chiefs: One of Alex Smith's qualities, for better or for worse, is that he's the same quarterback week to week and year to year. It's not difficult to predict his key stats, because they have generally fallen within a narrow range. Read more.

Los Angeles Rams: Yes, Jared Goff was the No.1 overall pick in the 2016 draft. And yes, he will have help in the backfield with Todd Gurley. But don't expect Goff to be the savior for a Los Angeles Rams offense that was near the bottom of every statistical category last season. Read more.

Miami Dolphins: If Ryan Tannehill makes moderate strides in the red zone, he could be in the 25-28 touchdown range. But will he amass 4,000 passing yards again? Read more.

Minnesota Vikings: The Vikings spent their offseason upgrading the weapons around quarterback Teddy Bridgewater. If they are going to make a run in the NFC, they'll likely be looking for bigger numbers from Bridgewater in 2016. Read more.

New England Patriots: It will be Jimmy Garoppolo's show for the first four games of the regular season before Tom Brady returns as the starter. While Garoppolo naturally isn't a top fantasy-football option, Brady is a slam-dunk choice for the final 12 games. Read more.

New Orleans Saints: Drew Brees may seem like a boring fantasy football choice in his 16th season. But if the rest of the owners in your league are willing to let him fall to you in the middle rounds of your draft, then you should be awfully excited about your team. Read more.

New York Giants: With an improved supporting cast and this being Eli Manning's third season in coach Ben McAdoo's offense, there is reason to believe he could only get better in 2016. Read more.

New York Jets: Coming off a career year, Ryan Fitzpatrick will be hard-pressed to duplicate his numbers from last season -- 31 touchdown passes and 3,905 passing yards. Read more.

Oakland Raiders: Derek Carr improved mightily on the stat sheet last season, but he faded in the second half. Another year of seasoning with his wideouts should bear sustainability. Read more.

Pittsburgh Steelers: Ben Roethlisberger has a high ceiling but is an unpredictable fantasy performer, and two suspensions could affect his numbers. Read more.

Philadelphia Eagles: Sam Bradford will start 2016 under center for the Eagles. The real question will be who finishes as the starting quarterback. That's why the low fantasy expectations for Bradford seem reasonable. Read more.

San Diego Chargers: Philip Rivers finished last season No. 2 in the NFL in passing yards and led the league in attempts and completions. Though he might not eclipse those numbers, he still should be among the league leaders again. Read more.

San Francisco 49ers: Drafting either Blaine Gabbert or Colin Kaepernick comes with a lot of uncertainty, and you should probably turn your attention elsewhere unless you play in a deeper league. Read more.

Seattle Seahawks: A strong second half in 2015 led to a career season for Russell Wilson, earning the Seattle Seahawks quarterback MVP consideration. What should be expected of him this season? Read more.

Tampa Bay Buccaneers: Don't expect Jameis Winston to hit a sophomore slump in 2016 -- his red-zone production should go up slightly, although he's not quite ready to be a top fantasy option. Read more.

Tennessee Titans: If Marcus Mariota stays healthy -- he is better equipped to do so, and the Titans are better equipped to help him -- he'll find the end zone more often. Read more.

Washington Redskins: The Redskins' offensive talent suggests they will be a pass-heavy offense. That makes Kirk Cousins an attractive fantasy football play. Read more.
