Maxx Crosby looked fast, fit, electric — and downright terrifying — on the first day of Raiders training camp Wednesday.

In other words, exactly how “The Condor” looks this time of year, as he ramps up to wreak havoc on anything in his path. That includes the unfortunate offensive linemen tasked with blocking him. And, by extension, the quarterbacks they’re paid to protect.

Which makes the Ravens’ decision to back out of a trade for Crosby last March look even more questionable.

Baltimore got cold feet over the knee injury Crosby was rehabbing from at the time of the trade — concerns that prompted a sudden reversal after initially agreeing to send two first-round picks to the Raiders to acquire him. 

On Wednesday, though, there was no sign of hesitation, limitation or anything resembling diminished explosiveness.

If anything, Crosby looked like a problem.

An angry one.

Which is exactly what the Ravens managed to create when they did the one thing you never do with someone wired like him: give him a personal edge.

“They pissed him off,” an NFL team executive said.

Crosby didn’t exactly dispute it Wednesday. Not directly, anyway.

“It’s been a long offseason,” he said. “But it’s a blessing in disguise.”

Don’t believe it?

Just ask his own quarterback, Kirk Cousins, who already sounds like a man trying to negotiate terms, reminding Crosby, and anyone within earshot, that quarterbacks are off limits this time of year.

“I’m just a little bit nervous that he’s got to respect the red jersey these next few weeks,” Cousins said. “So I’ll try to make sure that happens.”

Crosby hears it. He just isn’t built to operate that way.

“I just can’t tell you how many people have come up to me already like, ‘All right, so you know at practice you can’t do this,’” Crosby said. “I’ve got a whole textbook full of rules I’ve got to follow or I’m going to get in trouble.

“But that comes with it. I practice one way. I know I push the line. And sometimes I go over it.”

Pretty soon, those red jerseys will come off the quarterbacks Crosby squares up against. They’ll be replaced by Patrick Mahomes, Justin Herbert, Bo Nix and every quarterback on the Raiders’ schedule.

There will be no restrictions. No protections. No quarterback wearing a different color to signal he’s off limits.

Instead, one of the angriest and most feared pass rushers in the NFL will be unleashed, flying around the field with the same bad intentions that have fueled him his entire career.

And now a player who has piled up 69 ½ sacks in seven NFL seasons is carrying a chip on his shoulder as big as Mount Charleston.

“My mindset is I want to be the greatest at what I do,” Crosby said. “Period.”

Having covered Crosby for nearly his entire career, allow me to translate:

He’s saying he’s ready to make everyone pay for the perceived disrespect that came from Baltimore. Including, eventually, the Ravens themselves.

Good call.

For the Raiders, anyway.

As for the Ravens?

What exactly were they thinking?

They were a signature away from pairing Crosby with fellow pass-rush menace Trey Hendrickson to form the kind of edge duo that keeps offensive coordinators up at night. Yet they managed to talk themselves out of it at the last moment.

All over a knee that, judging by Wednesday, looked like a complete nonissue.

And in the process, they did the one thing you absolutely cannot do with a player wired like Crosby: give him a reason.

As if he needed one.

Now they get to live with it, watching from afar, or worse, dealing with it head-on, as that decision comes screaming off the edge every Sunday with their fingerprints all over it.

Well done, Ravens.

You didn’t just let Maxx Crosby walk. You created a problem the rest of the NFL now has to deal with.
