Largely an unknown commodity, J.J. McCarthy has “all the things” necessary to be successful in the NFL, and that is a direct assessment from former Minnesota Vikings fan favorite and two-time Pro Bowl wide receiver Adam Thielen.
McCarthy worked with Thielen during the offseason for the second year in a row. He has now left the Carolina Panthers’ playmaker impressed both times.
It is as encouraging as any review for Vikings fans to receive about their new QB1.
“He’s got all the things it takes to be a successful player in this league,” Thielen told KTSP Sports on July 17. “How I’ve gotten to year 13, he’s already got it. He’s got consistency, he’s got that mindset, he’s got all the skills to be able to play at a high level.
“I’m really excited, now, my second summer working with him, to see him get an opportunity, and to see what he does with the opportunity, because I see it now on the field. Just his mindset and all the things that it takes to be a great quarterback in this league, and I’ve been around a lot of great ones. He has everything you need. So I’m excited to see what happens.”
Thielen expressed similar sentiments following his first session with McCarthy in 2024. More encouraging, he is just the latest in a line of supportive remarks from Vikings legends.
J.J. McCarthy Winning Over Vikings Legends
The Vikings’ faith in McCarthy is well documented, from head coach Kevin O’Connell’s verbally backing the young QB to general manager Kwesi Adofo-Mensah signing off on the trade to move into position to select him with the No. 10 pick in the 2024 draft.
However, Thielen is part of a noteworthy list of Vikings franchise icons who have voiced their support for McCarthy.
Moreover, Thielen’s sentiments have been consistent.
“He’s got all the tools, that’s for sure,” former Vikings Pro Bowl wide receiver Adam Thielen said on “#92Noon!” in July 2024. “He can sling it. He’s super accurate. We’re in shorts and some T-shirts out there. But, yeah, that you can see a lot just from accuracy timing and those kind of things when you’re running routes on air.”
Love to see Justin Jefferson, JJ McCarthy, TJ Hockenson and Jordan Addison working out together. CJ Ham, Blake Cashman and Jordan Mason also joining in 😤

“He’s a baller; he’s definitely a baller,” ex-NFL QB Daunte Culpepper, who spent seven seasons with the Vikings, told KTSP’s Alec Ausmus in June 2024. “He’s a solid, solid young man, and he’s going to be an even better quarterback, I think. He has a lot of upside and a lot of ability.”
McCarthy also had a pleasant encounter with Hall of Famer Fran Tarkenton, thanking him for his blessing to wear the No. 9.
Thielen spoke to McCarthy’s personality, and it helps explain the draw.
“He’s got a maturity about him that you can tell that goes beyond his age,” Thielen said during his appearance on “#92Noon!” after his first workout with McCarthy. “I’ve really enjoyed being around him for the little time that I’ve been able to be around him, and [I’m] excited to kind of follow his career.”
McCarthy and Thielen’s chemistry could foster the right environment for a Vikings trade.
Vikings Trade Proposal Brings Back Fan Favorite
GettyAdam Thielen #19 of the Carolina Panthers warms up before facing the Jacksonville Jaguars.
Thielen is on a one-year, $8.5 million contract, and on a similar timeline with his career, with a Panthers team that should be improved but could still struggle to make the playoffs in 2024. A reunion with the Vikings could work for Thielen and make fans (and McCarthy) happy.
“I think I speak for most #Vikings fans, wishing they could see J.J. McCarthy throw passes to Adam Thielen on Sundays this fall,” Ausmus captioned the latest video of the duo.
This Heavy Sports Vikings trade pitch would send a 2026 late-round pick to Carolina for Thielen.
Vikings get:
- Adam Thielen
Panthers get:
- 2026 sixth-round pick
I think I speak for most #Vikings fans, wishing they could see J.J. McCarthy throw passes to Adam Thielen on Sundays this fall.
I got to watch McCarthy throw to Thielen today, Thielen says McCarthy's "got it."@KSTPSports pic.twitter.com/vA6gKvMoUK

The Vikings’ future draft capital situation is a bit convoluted, but they will have at least three Day 3 picks. The Panthers have two recent first-round picks, Tetairoa McMillan (2025) and Xavier Legette (2024). They also have a veteran (Hunter Renfrow) to replace Thielen.
Thielen would join a crowded Vikings WR room, too. It features Justin Jefferson and Jordan Addison. It also has young speedster Jalen Nailor and rookie third-rounder Tai Felton.
Still, Thielen can help and would not have to impact the Vikings’ upcoming cap crunch.
