A typical job in the front office of a professional sports franchise would be inside ticket salesperson. This role is directly related to the business and operations side of the franchise, focusing on ticket sales and customer relations.
The other options like "assistant coach" and "strength training VP" are more related to the team's coaching and training staff, rather than the front office. The "owner" is a higher-level position but not typically considered part of the front office team in the same way as ticket sales.
