Top Sleeper Quarterbacks for 2 QB & Superflex 2021 Fantasy Football Leagues

Two-quarterback and superflex leagues are the most fun ways to play fantasy football. The NFL is experiencing a passing boom right now, meaning there are more productive fantasy QBs than ever. Limiting your league to just 10 or 12 staring quarterbacks just isn't nearly as fun.

If you're making the switch to a two-QB or superflex league this year, The Duel has you covered.

Sleeper QBs Fantasy Football 2021

Here are three of the best sleeper quarterbacks, currently carrying an ADP of QB20 or higher, to target in two-QB or superflex leagues this season.

3. Derek Carr, Las Vegas Raiders (ADP: QB23)

Derek Carr is the most boring name on this list. But boring can be exploited in fantasy football. Carr was fantasy's QB13 last year, making him a high-end QB2. Despite that, he's currently being drafted as a backup in 10-team leagues. It's not like much around him has changed, either. He'll be playing in the same offensive system that he shined in last year, and the development of young WRs like Henry Ruggs and Bryan Edwards should only make this passing attack more dynamic. Plus, Las Vegas' porous defense should lead to a ton of volume for Carr. He's not going to be a league-winning pick by any means, but he feels like a shoe-in for top-15 QB production. That's a real value for someone who's not even being drafted as a starter. Carr checks in at QB19 in our 2021 fantasy rankings.

2. Trey Lance, San Francisco 49ers (ADP: QB21)

Trey Lance is pretty much the definition of a lottery ticket. His floor is as low as it gets; there's a chance he doesn't even see the field this season with Jimmy Garoppolo still sitting atop the depth chart. But if he does get an opportunity, watch out. The San Francisco 49ers' offense is a quarterback's dream, featuring QB guru Kyle Shanahan and one of the most talented skill-position groups in the league. It's hard not to salivate at the thought of Lance, who has Josh Allen-level physical tools, taking the reins in SF. The 21-year-old has recent history on his side as well. We've seen a rookie QB return top-10 fantasy production in back-to-back years now. And Lance is walking into a better situation than any other rookie QB has had in a while. Currently being taken outside the top 20, Lance has legit top-10 upside whenever he hits the field.

1. Tua Tagovailoa, Miami Dolphins (ADP: QB22)

Tua Tagovailoa's rookie season was a disappointment. There are very few numbers we can point to that suggest a year-two breakout is coming. He was routinely outplayed by journeyman QB Ryan Fitzpatrick, and he didn't display any of the special traits we saw at Alabama. But he's now even further removed from that devastating hip injury he suffered in 2019, and he's looking like a new man at Miami Dolphins training camp. If the Tua we saw at Alabama shows up in Miami, he's got huge upside. The Dolphins revamped last year's lackluster skill-position group by adding two explosive receivers in Will Fuller and Jaylen Waddle. This is an elite QB prospect playing in an explosive offense who is being drafted as a backup. That's a combination you won't see too often. If you take the plunge on Miami's signal-caller, be sure to pair him with a steady QB2 -- like Derek Carr -- as fantasy managers shouldn't totally ignore Tua's downside.
