What Dak Prescott's Injury Means For Andy Dalton

Dallas Cowboys QB Dak Prescott's season-ending ankle injury places veteran quarterback Andy Dalton in a starting role once more. Justin Carter evaluates Dalton's fantasy football outlook in 2020 as a waiver wire add.

On Sunday, Dallas Cowboys quarterback Dak Prescott suffered a season-ending ankle injury against the New York Giants. It was a horrifying moment for anyone watching the game.

With Prescott out, the Cowboys turned to Andy Dalton at quarterback to end the game. Dalton was 9-for-11 throwing the football, with 111 yards. He didn't throw for a touchdown or an interception, but lost a fumble.

Dalton will now be the starter for the Cowboys moving forward. And while we've heard all of the "lol Cowboys still have the best quarterback in the division" jokes over and over now, what are we really to make of Dalton in this role? Can he be successful enough for fantasy managers to make him a starting option?

Dalton's Past Performance

Andy Dalton brings with him something that backup quarterbacks don't always bring: a long track record of NFL performances as a starting quarterback.

That gives us some room to explore his past, though it's not as simple as just saying "he's thrown for 4000-plus yards twice, so he's going to be fine."

Instead, let's focus on Dalton's 2019 performance to start, since it was his most recent season and was fairly uneven, since he was benched for Ryan Finley for a time.

Still, Dalton started 13 games last year, which is good enough as a sample size. He completed 59.5 percent of his passes for 3,494 yards, 16 touchdowns, and 14 interceptions. The 14 picks were his most since 2014 -- that they came in three fewer games is definitely something that gives me pause.

Per PlayerProfiler, Dalton played on a Bengals offense that was fifth in passing plays per game last year. He was 11th among quarterbacks in attempts but just 18th in passing yards. A supporting cast efficiency that ranked 32nd among quarterbacks and protection rate that ranked 19th ere pretty big factors in that.

Still, even if we account for issues with who he was throwing the ball to, numbers like this worry me a lot:

I'm especially concerned by that clean pocket completion percentage. If the offensive line woes were really the main culprit of his inefficiency, wouldn't we have seen some improvement on his completion percentage ranking on those clean pocket looks? Or was he so rattled by the lack of blocking and weapons that nothing could have saved his 2020 season and he was destined to be bad even when he wasn't getting pressured?

Good question and one I don't have an answer to except to say that the last time the Bengals had an offensive line rank in the top 10 in lowest adjusted sack rate was 2014, when they ranked fifth. Dalton was a Pro Bowler that year, passing for 3,398 yards and 19 touchdowns, but he also threw 17 interceptions and had a QBR that was lower than the year before and after. So, maybe the line isn't the culprit for Dalton's struggles?

How He Fits Into This Offense

Well, the Cowboys run the most passing plays per game in the NFL this year, thanks in large part to a defense that can't keep the opposing team from scoring. That's meant Dallas has had to run more plays than they might otherwise be running.

It also should mean that they're forced to keep running pass plays. Maybe not at quite so high a rate -- Ezekiel Elliott will get more chances to run the ball, though I don't think Booger McFarland was correct at all about this take:

Yes, Zeke's a good running back, but the downgrade from Dak to Dalton doesn't somehow make you better just because it means three more carries per game for Ezekiel Elliott.

Anyway, the big question is how Dalton will play with a better supporting cast. Remember, he was 32nd among quarterbacks in supporting cast efficiency last year. Dak this year is 14th and was eighth last year. Dalton gets a huge upgrade to the players who he is throwing the ball to, which is going to help him play more efficient football. And a better protection rate will keep him upright, though it might not help improve his efficiency too much.

But hey -- Dak was a top five fantasy quarterback rest of season and averaged 29.6 fantasy points per game including his final game, and he did so despite not being top 10 in any of these things:

You can succeed in this offense without elite efficiency. So, even though Dalton does represent a decline in efficiency here, he can still be successful from a fantasy perspective because of the available opportunities for him.

This is, of course, assuming Dalton isn't completely cooked. Last year was bad bad, but he was throwing to the likes of John Ross and Auden Tate. Now, he gets CeeDee Lamb, Amari Cooper, and Michael Gallup. Considering the only consistent weapon he had last year was Tyler Boyd, I think this upgrade should help Dalton's efficiency. He was still 11th in accuracy rating last season, but 32nd in receiver target separation. In theory, Dalton should have some juice left and should be solid in Dallas.

Not Dak solid. But I'd project Dalton to be a high-end fantasy QB2 moving forward. He'll miss more than Dak. He'll throw picks more than Dak. He won't be as mobile. But he's also going to throw the ball a ton to three very good wide receivers, and Ezekiel Elliott's presence should open up passing lanes and the defense crowds the box a little more against Dallas.

Is There Dynasty Impact Here?

Could Dalton play so well that the Cowboys decide to let Prescott walk in free agency?

The answer to that is both yes and no. Yes, the Cowboys could let Dak leave if they don't feel comfortable with how much money he commands. No, Dalton's performance doesn't have an impact on that, and if Dak leaves, we'd expect to see the Cowboys draft a quarterback.

So, in terms of dynasty, Dak was a top-five dynasty QB before the injury. Because current-season value does matter, I might drop him a couple of spots, but he's still solidly a top-10 dynasty QB.

As for Dalton, his value does rise a good bit since we can assume he starts 11 games this year, but long term, he's about where he was, which is at the level of "solid backup." Yes, he should be universally rostered in Superflex. No, you shouldn't trade the farm for him, though a Dak manager in win-now mode might be fine with paying more than they should for Dalton right now.
