Final answer:
A player on the Detroit Lions who lives in Michigan would owe taxes to both the state of Michigan and the city of Detroit due to state income tax regulations and Detroit's city income tax.
Step-by-step explanation:
The question concerns the tax obligations of a player playing for the Detroit Lions and residing in Michigan. Such an individual would owe taxes to both the state and local authorities. Specifically, the player would have to pay state income tax to the state of Michigan as well as any applicable city income tax to the city of Detroit.
If a player is a resident of Michigan and earns an income, they are subject to the state's income tax regulations. Besides this, Detroit has its own city income tax which applies to residents. Thus, as a Detroit Lions player living in Michigan, the individual must adhere to the tax laws at both the state and municipal levels.
