If you want a glimpse into Pat Shurmur as the new head coach of the Giants, think of a slightly younger, much less round Andy Reid.

With the way they think about offensive football and the manner in which they interact with players, Shurmur and Reid are similar in many ways, which is hardly surprising, considering Shurmur sprouted from the Andy Reid coaching tree.

“Stylistically I do think they’re pretty similar,’’ Mitchell Schwartz, the Chiefs’ top-notch right tackle, told The Post. “I’m sure Coach Shurmur modeled a little bit of that after Coach Reid. It seems like all those guys have that same philosophy where you coach accountability and you surround yourself with the right people, you kinda set those standards and the players follow them.’’

The Giants and Shurmur — the Vikings offensive coordinator — made it clear Monday, without uttering a word in public, they want each other, although nothing can be made official until after the Vikings are done playing. That could be as soon as after the Vikings-Eagles NFC title game in Philadelphia on Sunday night or as late as Feb. 5, the day after Super Bowl LII.

Either way Shurmur, as the 18th head coach in team history, will inherit a Giants-sized mess, a team that bottomed out to 3-13 in 2017 and needs a firm hand to push this franchise back into contention.

Shurmur has that firm hand and an Andy Reid persona, according to Schwartz, who knows of what he speaks. He was a rookie in 2012 in Cleveland when Shurmur was in his second season as the Browns’ head coach. For the past two years, Schwartz has anchored the offensive line in Kansas City for Reid, the Chiefs’ head coach.

“I do think the demeanor is similar in terms of the style of coaching, where they have really high expectations, they tell you the goals, what you need to accomplish and they’re not gonna berate you, they’re not gonna yell and scream at you,’’ Schwartz said. “They’re gonna hold you to a high standard but they’re gonna do it in a way that’s conducive to learning and getting better.’’

Reid was an offensive tackle at BYU; Shurmur was a center at Michigan State. There is a certain down-to-earth, grind-it-out nature with most offensive linemen.

“I think you could tell just by talking to him, he still had that part of him in his heart,’’ Joe Thomas, Cleveland’s star left tackle for 11 seasons, told The Post of his two years with Shurmur. “Even though he sort of made his name in the NFL as the quarterback guru, sort of as a passing, West Coast guy, you could tell he was still a lineman at heart and still liked talking lineman stuff with the rest of the guys.’’

The concern with Shurmur is his ability to motivate. The Browns in 2012 started 0-5 and went 5-6 in the final 11 games, a testament to the steady hand Shurmur showed to Schwartz, then a rookie offensive lineman starting all 16 games.

Is he a leader of men?

“I think he is for sure,’’ Schwartz said. “Obviously, going back, Cleveland is not the most successful place for head coaches the past few years. That shows his ability to lead a team and keep us on track. We started out very, very poorly and it would have been easy to just pack it in and just ride out the rest of the season. That’s an area where you can look at a coach and ask how did he respond to that, did he get the guys on track? I think he did. That’s a big plus.’’

Shurmur won nine games in two seasons with the Browns. His head coaching debut in 2011 lined up with the NFL lockout and his second year ended with the sale of the team and thus the inevitable desire for a clean slate.

“I thought Pat did a pretty good job from where we were to where we ended up when he got fired,’’ Thomas said. “The team was definitely headed in the right direction. We certainly were playing better and given a couple more years we could have turned that team into a playoff contender.’’

Shurmur did not get a third season in Cleveland, and soon enough, he will get the chance to make an impression in his first year with the Giants, a team in need of fresh ideas.

“I think he’s a great motivator, great leader. Not all leaders are fire and brimstone,’’ Thomas said. “I see it a lot of the same way a guy like Andy Reid motivates. The respect you have for him and his intellect and what he brings to the game of football and what he demands out of you is the way he gets the most out of his players.’’
