-- A high school football star in Pennsylvania got what most players dream of: several scholarships to Division I schools. But after 18-year-old John Castello saw the movie "Concussion," he decided the potential health risks the game poses isn't worth the free ride to college, so he turned them all down.
"I thought it would shed some light and help me make a decision on whether I should play football or not," he said.
"Growing up a Steelers fan, everyone loved Mike Webster," he said. "To see what he went through, because of football, that really hit me hard."
Castello said witnessing the misfortunes of former football players, from the high school to the professional level, has served as a cautionary tale and aided in his resolution to stop playing.
"They've attempted suicide, gone bankrupt, broke,homeless -- and at a young age -- not older, but in their 40s and 50s," he said. "That’s very concerning to me."
The high school senior has received some flack from fellow students and recruiting coaches who have called him "soft" or "too scared" to play.
"They didn’t understand where I’m coming from," he said.
His high school football coach called him a "great football player."
"I don’t think there’s any doubt about that," Mars Area High School head football coach and athletic director Scott Heinauer told ABC News today, citing the level of recruitment Castello experienced.
"He’s a great kid," Heinauer said. "No matter what he does in life, John will be successful."
Castello said the thing he'll miss most about football is the brotherhood, but the 6-foot-5-inch, 225-pound tight end and defensive end decided to focus on another sport he's been playing for almost 10 years: basketball. But the decision was made even more difficult by the fact that he hadn't yet been offered any basketball scholarships.
"It was very, very hard to choose,” Castello said, but added that it's "probably the right choice" for the future.
Castello's basketball coach, Rob Carmody, said the "prominent" athlete isn't trying to make "a statement for everybody else."
"This was a very personal decision that John made, Carmody said. "It’s not easy to walk away from a free education when the opportunity may not be there in basketball."
He already has a partial scholarship offer from Shippensburg University and a full scholarship offer from the University of Pittsburgh at Johnstown, and more offers are continuing to trickle in, Carmody said.
Wednesday was National Signing Day, when high school students sign a binding letter of intent for college football. Castello said he has "no regrets" about not participating in it.
"I’m very happy for all the guys who signed today. That’s great for them," he said. "But, I’m very happy with choosing basketball. I really love basketball."
The Mars Area High School student still has several friends and teammates who plan to further their football career, he said, and some have even been offered scholarships to play. He said that he "respects" their decision and will be praying for them.
"That's their decision, and they know the consequences that can come with playing college football, Castello told ABC News affiliate WTAE in Pittsburgh. "But, they're tough kids and they really love the game, so I think they're going to do it."
The director of "Concussion," Peter Landesman, reached out to Castello through WTAE after hearing about his story.
"[Landesman] just said he wanted to commend me for what I’m doing," Castello said. "He said, 'Sometimes you’re going to face difficulties like this in life.'"
Castello achieved his 1,000th rebound in yesterday's game, Carmody said. He will spend the rest of the school year trying to win a basketball state championship alongside his twin brother, Steven. He said, they will graduate from high school in June.
