Chariot Journeyman
Similar to how Formula 1’s team system is set up, the Ancient Rome chariot scene was divided into different teams by color. Upon coming to Rome, Gaius drove for the White Team, the lowliest of the four factions. By age 24, he was recruited into the Green Team. Three years later, he was driving for the Red Team, which was an iffy move on his part since the Green Team was much better off and recognized as being more elite.
In modern sports, a journeyman is someone who is competent at the sport they play but is unable to excel. They play for different clubs or teams in a short time period, usually receiving smaller paychecks as opposed to their superstar peers. Gaius was somewhat of a journeyman himself, but his decision to move teams stemmed from an undying thirst for money.
Gaius’ underlying reason for signing with Red and leaving Green was for money and to be the best charioteer of his team. He immediately became a superstar among his more amateurish teammates, earning several times more than the others. Plus, his showmanship and from-behind victories had the crowds jumping to their feet every time, which would make him even wealthier than he already was.
