Should I try to talk to him?

Two years ago a boy in my class liked me. He made it really clear, always attempting to talk to me or make me laugh by just acting goofy. He even flirted with me in front of his friends and genuinely acted like he cared, instead of acting like a jerk like most guys do in front of their friends. The only problem was, he was (and still is) a football player, and I was afraid of getting hurt, because they have such a bad reputation of being players. Now we’re seniors and more mature, but I have no classes with him. I’ve seen him standing alone in the hallway and he looked at me but I was too nervous to say anything. It was almost like he wanted me to make a move, but I didn’t, and I’m afraid it might be too late now. We are friends on facebook, but with his busy schedule, he never gets on, so I don’ t know how or if I should try to talk to him after making him look pathetic two years ago?
