The 5-foot-11, 180-pounder, who previously played for Corona (Calif.) Centennial, had actually been at Lamar during his freshman season.
"I was here freshman year, so it I know everybody on the team and I know the coaching staff. It's really just getting back to my roots. Of course it's a little different, some different terminology, but it's been great to come back," he said.
Plattenburg has embraced the experience and has enjoyed working with his new, but old, teammates.
"It makes you know how much you missed them. I've always kept up with these guys. I went to state last year, too, and we lost, so I know how they feel. I'm just as hungry as they are. It's been great," he said.
On Friday, Plattenburg also received another taste of playing football in Texas.
"There's a lot more dry heat here," he laughed. "That first game…phew."
The four-star prospect recently attended The Opening, where he impressed Scout's national analysts.
"It was the best football experience of my life. It was great talking to people who have been to the highest level before and learn what you need to do to get there. Work ethic, social media, your friends, goals, and of course, new techniques on the field. I really see it as an advantage, especially working with the NFL players. I learned a lot," he said.
The past few months have also been busy in regard to recruiting, as Plattenburg now holds twenty offers.
"It's been crazy, but it's a once in a lifetime thing. I'm taking it in and embracing it. I'm at twenty, and Duke and Tennessee could be close to offering," he said. "I'd say Washington, Baylor, California, Vanderbilt, and UCLA have been recruiting me the hardest."
With so many offers, it's difficult for Plattenburg to name any favorites.
"No one is really standing out right now. I loved Washington when I went up there last week, it was great. But I have to come back home and get down off of the visit high and I'm really taking it in and evaluating everything right now," he said.
Though no visits are planned just yet, there are a few schools that the athlete would like to explore.
"I've been to the West Coast teams, so I would love to go see Duke, Vanderbilt, and Tennessee if I get the chance to. I definitely want to go see those schools," he said.
Plattenburg is enjoying the experience and says that he does know what criteria he's hoping to land in a program.
"I'm looking for a place with a great atmosphere. I want to know that even if a coaching change happens when I'm there, the school is still the right place for me. A great education is number one out of everything. I look at the depth chart, but I'm going to play hard wherever I go," he said.
Aside from recruiting, Plattenburg is continuing to work on his game and learn all he can at both defensive back positions.
"I was really taking this spring as time to better myself as both a corner and a safety. The first time I ever played corner was in the first game of the playoffs. For only five or six games, I think I did pretty well.
"In college, I think I could possibly be both [corner and safety]. I've really been working at corner and I know I have the athleticism. I want to keep working, but I think corner will be my go-to," he said.
