NFL rules prohibit Mitch Trubisky from even talking football with new coach Matt Nagy until April 3, so the Bears franchise quarterback is taking steps on his own to prepare to learn Nagy’s new offense.

He has been studying video of the 2017 Chiefs, who ranked second in the NFL in yards per play with Nagy as coordinator.

“I can’t wait,” Trubisky said in an interview Sunday. “It’s going to be very explosive.”

From the second-year quarterback’s perspective, there’s a lot to like, including the misdirection option concepts and the variety of throws.

“We’re going to see a lot more quick passes, RPOs (run-pass options), screen game, get-the-ball-out, deep-ball shots — everything that I’m good at that you’ve seen at North Carolina and some stuff we even ran last year,” he said.

“We’re just going to do even more of it and get the ball to our playmakers out in open space. And just hide the ball, play-action, more flashy stuff in the backfield to hide the ball. It’s not just going to be run it right at you. It’s going to be more tricky stuff.”

Trubisky sees significant overlap between himself and quarterback Alex Smith, who played for Nagy and Chiefs for the last five seasons before being traded to the Redskins this offseason.

“We both throw the deep ball,” Trubisky said. “Accuracy. Get the ball out quick. Both very mobile. And just play smart, play accurate, get the ball to your playmakers and let them do the work. Just get the ball out quick so you help the O-line out. So I feel like it’s going to be a great offense for the players we have.”

That supporting cast was fortified at the start of free agency. General manager Ryan Pace signed receivers Allen Robinson and Taylor Gabriel and tight end Trey Burton last March 14 to increase the potency of an offense that ranked last in total passing and 25th in yards per pass last season.

Even closer to Trubisky, Pace has constructed a quarterback incubator of sorts. Nagy is a former Arena League quarterback, and newly-signed backup quarterback Chase Daniel worked under Nagy with the Chiefs from 2013-15.

Daniel, who also backed up Drew Brees with the Saints in separate stints (2010-13, 2017) was asked Thursday what it takes for a quarterback to succeed in Nagy’s offense.

“A brain,” he said.

“It's very quarterback-intensive,” Daniel continued. “It's not just go out there and throw to the open guy. It's very specific from a quarterback perspective in terms of splits by receivers, what route does a tight end have on this concept, where the running back is, the depth of a running back, how many yards on a ‘ZD’ bend. It's very quarterback intensive, and as a quarterback we're supposed to know that stuff. I'm looking forward to teaching Mitchell.”

Trubisky is aware Nagy requires his quarterback to master so many adjustments, and he believes that fits his ability and passion.

“I feel like there’s more responsibility on my plate,” Trubisky said. “It’s not just going to be one play. There’s going to be a lot more checks and audibles at the line of scrimmage. Hand signals to change routes, protections. The new protections, I kind of have already been going through them on film on my own. And just in my head they make a lot more sense.

“I can’t wait to dive in with the coaching staff once we get started. Yeah, it’s just going to be new. But I feel like that’s a strength I had coming into the league. I’m a student of the game. I have a football mind. I like to just go back to my house in my office and study the game and make sure I know my job inside and out.”
