Patrick O'Brien isn't just sitting around watching Netflix during his spring break.

Back in his home state of California, the Husker third-year sophomore quarterback is working with his private QBs coach Steve Calhoun. That's not the only one he's working with. Someone has to catch those passes, and it's even better when that someone is five-year pro Keenan Allen of the Los Angeles Chargers.

@oneandonlyPOB 2 @Keenan13Allen !! These guys had great chemistry all day today’s! This is a great start to spring break! I’m looking forward to the rest of the week, with more of my College Jedi’s in https://t.co/GGTncaNVAA for break! @HuskerFBNation @Huskers #armedanddangerous pic.twitter.com/sBujy9KFAM — Armed&Dangerous QB (@ArmedDangerQBS) March 20, 2018

Calhoun has worked with both O'Brien and Husker redshirt freshman quarterback Tristan Gebbia since they were in middle school.

The coach spoke with Nebraska247 earlier this month about both quarterbacks' mobility, and how he feels they can operate in Scott Frost's offense.

"When I'm around either one of them, we're always talking ball," Calhoun said. "We're always talking football and how to get better. As you know, the quarterback side is like 90 percent mental. And so they're always picking my brain on things they can get better from the mental aspect of the game, whether it's understanding protections or coverages. They're football junkies when it comes to that."
