EAGAN, Minn. — Justin Jefferson plans to work with both J.J. McCarthy and Kyler Murray during the break ahead of Vikings training camp.

Jefferson spoke to Twin Cities media members Thursday as Minnesota wrapped up mandatory minicamp and anticipates it will "be impactful" to put more time on task with the pair of QBs vying for the starting role.

"We're gonna continue to do the same things we're doing here but at a different location," he said.

Jefferson has observed progression in both passers — Murray as he's worked to learn a new offense after spending seven seasons in Arizona and McCarthy coming off his first 10 NFL starts.

Murray and McCarthy shared first-team reps throughout voluntary Organized Team Activities and minicamp, meaning Jefferson's caught multiple passes from each of them.

" 'Growth' is the key word [for them]," Jefferson said. "And obviously having a new quarterback in Kyler, just trying to work with him, building that connection with him. Working with J.J. and seeing the impact and the growth and the improvements he's made, it's definitely tremendous.

"I'm seeing great work [from] everybody in this whole entire [minicamp]," he continued. "I'm really glad to see everybody here and working as a team and building that team camaraderie early. It's just great to see everybody, great to get in that work again and carry that on throughout the summer."

Jefferson noted McCarthy's implemented the experience he added last year and has shown improvement in reading coverages and making different throws: "Everything doesn't have to be a hundred miles per hour; some throws he can put a little touch on it and get it to the spot."

And as McCarthy furthers his development, Jefferson is fostering his understanding of the younger quarterback, as well as Murray, and how they both operate on and off the field.

"They're two different quarterbacks," he said. "They both throw differently. They each have a different mindset. It's all about continuing to work with them, continuing to have the work outside of this building."

Jefferson described Murray as "a real cool guy" who maintains a calm demeanor.

"Chill," Jefferson said, smiling.

He and Murray have engaged in easy sideline conversations to learn more about what the other needs on the field, and Jefferson is seeing that connection build.

"A new receiver that he's throwing to, he's trying to learn my route running, learning my moves, learning when I'm gonna break, learning how fast I'm running — all of those different things a quarterback needs to throw the ball," Jefferson said. "Just working with each other, trying to build that chemistry."

Time will tell whether Murray or McCarthy ultimately will be throwing to "Jets" in-season.

But for now, Jefferson is simply focused on establishing connection with each of them and working to improve himself every day.

He emphasized the final decision will eventually come down to Head Coach Kevin O'Connell, and he's intentional to not worry too much at this stage over which QB comes out ahead.

Jefferson listed both skills-based and intangible traits O'Connell and his staff will be watching for, from execution of plays to adjusting on the fly and being a vocal leader in the locker room.

"At the end of the day, somebody's going to have that job, whether it's Kyler or it's J.J.," Jefferson said. "So it's just all about working with both of them to make sure whoever is the starter, we're dialed in, we're ready to go … when the season starts."
