Joe Schoen, of course, wants to select defensive players in the upcoming NFL draft who are perfect fits for Wink Martindale’s scheme.

The second-year general manager has a better feel this time around as to what a “Wink player’’ embodies after he has spent a full season watching the aggressive, blitz-happy defensive coordinator deploy his personnel.

Is there a danger in finding and fitting players into a specific system, only to have the coach of that system leave?

Earlier in the offseason, Martindale interviewed with the Colts and he has made no secret of his desire, at age 59, to become a head coach, sooner rather than later.

“Yeah, it’s actually something that coach [Bill] Parcells told me a long time ago,’’ Schoen said Thursday. “He told me, ‘Coaches come and go. You need to draft good football players.’ Yeah, you don’t want to get too pigeonholed into scheme-specific, because then if Wink gets a head job a year from now and you bring somebody else in that runs a totally different defense, you have a scheme-specific player.

“Part of our job is to balance that. Like, does this guy add value? Like, he’s only going to fit this one scheme. And yeah, Wink’s got a really good chance to get a head-coaching job. If he moves on and we change things up, then yeah, you definitely have to balance that and be aware of that.’’

Schoen said the greatest learning curve he had to navigate was figuring out what sort of skill sets Martindale prefers for his front seven: the defensive linemen, edge rushers and inside linebackers.

The Giants are in the market for a cornerback, which they may target, along with wide receiver, with the 25th-overall pick.

“There’s a better comfort level, not just myself but even [head coach Brian Daboll],’’ Schoen said. “Dabs had never worked with Wink, either. As we’re going through it, how he’s going to utilize players first down, second down, third down. So yeah, there’s definitely a better comfort level this year, but I wouldn’t say we weren’t necessarily aligned last year.’’

Schoen said there was a certain amount of having to “retrain a little bit’’ to make sure he and the scouts focused on exactly what Martindale wants to make his defense run at peak efficiency.

“What’s most important is what is the value for the Giants and how do we see them and how they are going to be utilized; we are still having those conversations,’’ Schoen said. “We definitely had to retrain how we think about some things at different positions and what the value of those traits are that we covet and where those align in the draft. But definitely feel better going into it this year in terms of what exactly he’s looking for.’’
