The dynamic wide receiver and talented quarterback, who have their rabid fan base already in a lather just five days into training camp, pose for photos, shake the hands of the folks lucky enough to secure on-field passes and seem to be in no particular hurry to escape the nearly 90-degree temperatures.

Long after that dynamic duo retreats inside, another player walks alone toward the locker room, his orange helmet and shoulder pads in one hand and an energy drink in the other. No one asks him to stop for a photograph or sign an autograph, but the young man, who is No. 89 on the roster and battling everyday for a chance at a roster spot, appears right at home.

Stephen Carlson — one of Jamestown’s favorite sons — is living the dream.

Carlson graduated from Jamestown High School in 2015 after a dynamic athletic career. A two-time first-team all-state selection for the Red Raiders, he was also The Post-Journal’s Player of the Year his senior year. That same season he was the recipient of the Connolly Cup, awarded to Western New York’s top player.

Carlson later moved on to Princeton University where his performance for the Tigers his last two seasons as a wide receiver drew the interest of several NFL teams, enough so that he was signed as an undrafted free agent by the Browns three months ago.

Since then, it’s been his mission to see how far he can go with the opportunity he’s been presented.

So far, he maintains, so good.

“I think I’ve been doing well,” he said after Monday’s practice. “I’ve been playing hard and playing fast, (but) I definitely have a lot of work to do.”

Not only has he had to adjust to competing with the pros, but he has had to do so while learning a new position — tight end.

“Switching positions, there’s so many little techniques and looks the defense will give me that I haven’t seen before,” said Carlson, who has added 15 pounds and now carries 240 pounds on his 6-foot-4 frame. ” … There’s definitely a lot of work to do.”

Running on Monday with the third offensive group, comprised mostly of rookies, Carlson caught several passes, did individual position drills and even took part in special-teams activities, including blocking and punt return coverage.

“I’ve seen kind of what it takes just from watching the older guys,” he said. “I think I have that stuff in me, and I’m ready to work hard the rest of camp. I think in a couple days I’ll really start feeling good, and I’ll get all my technique together, mesh and everything should be going well. I’m excited for the next couple days.”

The Browns have today off, but Carlson expects he’ll stop by the facility for lunch and an ice bath.

“It’s been long days and I’ve been tired, here and there, but I’ve enjoyed it,” he said. “I’ve been excited to learn and come out every day and get better. Just in five days, I’ve seen myself getting better and better. I’m excited for the next couple weeks.”

When Carlson was growing up, he and his older brother, Chris, were Pittsburgh sports fans and would attend Pittsburgh Steelers’ training camp. On several visits they were fortunate enough to secure autographs of some of the players.

“We never really got any big-name guys,” he said, laughing at the memory. ” … Every year we’d always get the guys nobody knew. We never really knew them, but we were just little kids and we started loving them. We followed them on the Internet and everywhere they would go.

“I was signing autographs the other day, and I was thinking they have no idea who I am. It was kind of funny.”

Carlson has a little more than a month to make his name known on a team that, for the first time in decades, has big, big expectations.

“We’ve got a nice group of tight ends here, so it will be a challenge to make the roster, for sure, but I’m not putting anything past myself,” he said. “I’ll be going at it these next couple weeks, hopefully string some nice preseason games together, get some film out there and see what happens.”

As for his childhood love for the Black & Gold, Carlson smiled before answering.

“I can’t be a fan anymore,” he said.
