Here’s some of the broad topics covered in the first hour.

>> Pelini touted new assistant coaches Rick Kaczenski and Terry Joseph as low-ego, no-nonsense, high-energy fits for his coaching staff. Both are “outside-the-box” thinkers whose coaching techniques Pelini has followed for several years.

“He really fit into how we play,” Pelini said Kaczenski. “But at the same time, I’m always picking his brain about different ways to do things.”

Joseph, meanwhile, is a “global thinker,” “the total package” and “as good there is,” Pelini said, and destined for a defensive coordinator job somewhere.

“And I don’t say that about a lot of people,” he said.

>> Bo hasn’t talked to brother Carl Pelini — Florida Atlantic’s new head coach — in “a couple months.”

“I haven’t talked to him this summer,” Bo Pelini said. “He’s going to do it his way. I got enough to worry about.”

>> Not much chatter about Taylor Martinez, his throwing motion, or his progress at quarterback Friday. Pelini shut down the line of questioning quick. Pelini said Martinez — who visited personal quarterback Steve Calhoun this spring for the first time — has been working on his throwing mechanics “since I’ve known him.”

Asked about Martinez’s growth as a total quarterback, Pelini said: “I think he’s made great strides. I can sit here and talk about it and you guys will sit there and write that you don’t buy it. Because I know you’re going to write that. And we’ll find out when the game comes. Is that fair enough? Because I know that’s what goes on. That’s why you’re asking.”

>> Pelini’s heard “really positive things” about freshman quarterback Tommy Armstrong this summer. The Cibolo, Texas native has a chance to play this fall if “he’s one of the best guys.”

“We’re going to play you unless you’re not ready,” he said.

>> The defensive secondary will be better because it’s deeper, “more grown up” and experienced. Pelini said nickel Ciante Evans had a big spring camp at his spot.

“He was a force inside,” Pelini said.

Pelini mentioned Andrew Green, Antonio Bell, Mohammed Seisay, Daniel Davie, Charles Jackson and Stanley Jean-Baptiste as guys fighting for time at corner. Had NU named a starting secondary after spring ball, Bell would have been one of the starting corners.

>> Will Compton, Alonzo Whaley and Sean Fisher are the top linebackers right now.
