Richie says that he met Fonzie three-and-a-half years ago at the start of his sophomore year in high school. At the time, he says, Fonzie was still a member of the Falcons. However, when the show first started, Richie was in the middle of his freshman year (determined by subtracting three-and-a-half years from his current situation), and he already knew Fonzie very well. In addition, Fonzie was not in the gang at that time. To further complicate the issue, Richie states in "All the Way" that he is a junior. If that was true, he'd be a junior in college at the time of this episode, but he's really only a freshman.
