Most sports he wasn't great at and he was kind of lazy. He enjoyed the social aspect and being with his friends. I'm certain some parents thought he sucked and wondered why he was playing.
At age 14-15 he hit a little puberty and his body changed. He got taller. Stronger. Faster. All state in football as a junior and senior. Only kid in his peer group to play D1 ball. 3 year D1 starter on defense.
Maybe don't judge a kid too early or harshly.
