The Leesville Road standout, whose father played for the Pirates, is happy about his decision.
"It's definitely a big relief to be done with the recruiting process -- especially being committed to ECU," said the 6-foot-3, 290-pound Winstead. "Now, I can focus on my senior season without any distractions.
"The main thing that led me to my decision is that I've been a Pirate fan my whole life and I could always see myself playing for them. I also love the whole coaching staff and know they will do great things at ECU."
He could play multiple positions for ECU.
"They are talking about me mainly playing center, but also being able to rotate at guard," Winstead said. "(Offensive line) coach (Geep) Wade has also mentioned me possibly playing as a true freshman, but I don't know anything for sure."
The coaches played a major role in his decision.
"I have very close relationships with coach (Scottie) Montgomery and coach Wade," Winstead said. "They are awesome coaches on and off the field, and you can tell they really care about their players and the community."
Winstead is looking forward to playing for Montgomery.
"I am extremely excited to play for him," Winstead said. "I love his energy and enthusiasm. ECU will be unstoppable under his leadership."
He joins Greenville (N.C.) Conley quarterback Holton Ahlers in ECU's 2018 class.
