Giants coach Pat Shurmur’s seat is broiling.

Shurmur’s Giants are 2-8 and have lost six straight games — most recently to the hapless Jets. Shurmur went 5-11 in his debut season with the Giants, last year.

Shurmur has three years left on his contract after 2019, so it’s not a lock that co-owner John Mara would fire him. But if things don’t improve the final six games, Shurmur should be gone.

So let’s rank the top 12 candidates Mara could hire to replace Shurmur in 2020, with an eye on developing high-profile rookie quarterback Daniel Jones.

These rankings go from “worst” to “best” — and that’s all very subjective, of course — as we see things right now.

12. Kris Richard, Cowboys defensive backs coach/passing game coordinator: He is a well-respected leader, and he’s eventually going to land a head coaching job. He just turned 40, so he is considered one of the NFL’s fast-rising, young head coaching candidates. But considering the Giants’ top priority — developing Jones — it seems highly unlikely they would hire a defensive-minded coach to replace Shurmur.

11. Dan Campbell, Saints tight ends coach: He has received head coaching buzz in recent offseasons. And his experience under Sean Payton in New Orleans is a plus. Remember, Mara knows Payton because he worked for the Giants from 1999-2002. Campbell, 43, is a legit, young leader. He started his playing career with the Giants, from 1999-2002. But does Mara want to hire a coach with zero coordinator or quarterback-developing experience?

10. Robert Saleh, 49ers defensive coordinator: A relatively new name to the head coaching buzz scene. Expect him to attract significant interest for the first time in 2020. Saleh is in his third season as the 49ers’ defensive coordinator. He has done some encouraging things. But unless the Giants are able to land a guru offensive coordinator/quarterback developer, it’s unlikely they’ll aim for a defensive-minded head coach as Shurmur’s replacement.

9. Kevin Stefanski, Vikings offensive coordinator: He has gotten the most out of quarterback Kirk Cousins, tight end Kyle Rudolph and running back Dalvin Cook, in a similar scheme to what Shurmur built with the Vikings — and is running with the Giants. The biggest hurdle Stefanski would likely need to clear as a candidate — convince Mara he isn’t just Shurmur 2.0, which could be a tall order.

8. Shane Waldron, Rams quarterbacks coach/passing game coordinator: Will the Zac Taylor mess in Cincinnati scare teams away from Waldron? Taylor, 36, is 0-9 as the Bengals’ first-year head coach, after being the Rams’ quarterbacks coach. Waldron, 40, replaced Taylor in that role with the Rams. Waldron has zero NFL or college play-calling experience, in terms of being a full-time offensive coordinator. That’s probably less than ideal.

7. Greg Roman, Ravens offensive coordinator: He has made a habit of creating interesting formations that move weapons around the field, to open up opportunities for mobile quarterbacks like Colin Kaepernick and Lamar Jackson. If anyone can figure out how to scheme running back Saquon Barkley open in space — and maximize Jones’ mobility — it’s Roman.

6. Lincoln Riley, University of Oklahoma head coach: Seems unlikely for any NFL team at this point. Oklahoma just gave him a lucrative new contract this past offseason. He is making $6 million this season. In a lot of cases, high-profile college coaches earn more money than NFL coaches. His offensive chops are intriguing, even though he is just 36. But we can’t put him higher on this list simply because it seems unrealistic that he leaves Oklahoma.

5. Nick Sirianni, Colts offensive coordinator: Like Saleh, he is a relatively new name. But he has ascended fast, considering what the Colts have done, post-Andrew Luck. Yes, head coach Frank Reich obviously deserves a huge amount of credit. But so does Sirianni. He is in his second season as Reich’s offensive coordinator. Sirianni, 38, was the Chargers’ quarterbacks coach from 2014-15. An intriguing young name to watch.

4. Josh McDaniels, Patriots offensive coordinator: Bill Belichick assistants often struggle to replicate the Patriot Way when they leave. But McDaniels might be the exception, because this wouldn’t be his first NFL head coaching job. He went 11-17 in Denver, then returned to New England — and (most recently) jilted the Colts, who wanted him to be their head coach. Could McDaniels do with Jones what former Patriots offensive coordinator has done with Deshaun Watson in Houston?

3. Matt Rhule, Baylor University head coach: He has galvanized Baylor’s program, following a sexual assault scandal. Before that, a strong run at Temple made him a hot coaching commodity in college and the NFL. Last offseason, Rhule interviewed for the Jets’ vacancy and was a finalist for the Colts’ job the previous year. His experience on Tom Coughlin’s staff and impressive recent track record likely will vault him onto the Giants’ short list.

2. Eric Bieniemy, Chiefs offensive coordinator: Andy Reid has a highly successful coaching tree. Bieniemy could be the next branch. Bieniemy helped oversee the development of MVP quarterback Patrick Mahomes. Last season, with Bieniemy’s input (though he doesn’t call plays), the Chiefs gained 425.6 yards per game. Imagine what Bieniemy could do with Barkley, Sterling Shepard, Golden Tate and Evan Engram as weapons for Jones.

1. John DeFilippo, Jaguars offensive coordinator: Potentially the best candidate available to oversee Jones’ development. Not only did DeFilippo make mechanical adjustments to Carson Wentz’s throwing motion entering Year 2 — which vaulted him into the MVP conversation — but he managed to turn Nick Foles into a Super Bowl MVP and Gardner Minshew into a competent NFL quarterback. DeFilippo’s prowess as a quarterback whisperer and experience as a play caller should put him in high demand this offseason.
